Introduction A source code control system is a MUST to manage the changes occurring to a software project during development. Developers need a complete history of changes to backtrack to previous versions in case of any problems. Since source code is the most vital component of any software project and software development takes a huge amount of time and money, it is very important to spend some time in safe-guarding the source code by using source code control systems like CVS and RCS. CVS (Concurrent Version Control System) is a powerful tool which allows concurrent development of software by multiple users. It uses RCS underneath and has an application layer interface as a wrapper on top of RCS. CVS can record the history of your files (usually, but not always, source code). CVS only stores the differences between versions, instead of every version of every file you've ever created. CVS also keeps a log of who, when and why changes occurred, among other aspects. CVS is very helpful for managing releases and controlling the concurrent editing of source files among multiple authors. Instead of providing version control for a collection of files in a single directory, CVS provides version control for a hierarchical collection of directories consisting of revision controlled files. These directories and files can then be combined to form a software release. CVS can be used for storing "C", "C++", Java, Perl, HTML and other files. 2. Which One Is for Me? CVS or RCS CVS actually uses RCS underneath. CVS is a lot more powerful tool and can control a complete source code tree. It is very strongly recommended that you use CVS, because you can greatly customize CVS with scripting languages like PERL, Korn and bash shells. See the sample korn shell scripts at ``''. Advantages of CVS: · CVS is decentralised so a user checks out files/directories from the repostitory and have his own separate stable source directory tree. · CVS can "STAMP" releases of an entire project source tree. · CVS can enable concurrent editing of files. · CVS can be greatly customized to enable strong locking of files via shell scripts or PERL scripts. CVS supports weak locking with the command 'cvs watches' and also no locking permitting concurrent editing of files. Disadvantages of CVS: · Needs a little more administration than RCS. · Very highly sophisticated and complex system. It is "State of the Art" technology. The cvs software is a very advanced and capable system developed over a very long period of time (it took several years!!). · Has a large number of commands and command options, hence a steeper learning curve for beginners. The shell scripts at ``'' can ease usage. Advantages of RCS: · RCS is very simple to setup, with less administrative work. · RCS is used in a centralized area where everyone works. · RCS is useful for simple systems. · Very strong locking of files - concurrency eliminated. Downside of RCS: · Concurrent development by multiple developers is not possible due to file locking and being limited to a single working directory. Because of the single working directory limitation, changes to files by multiple developers can cause failure of the 'make' command. · Cannot stamp releases of an entire software project. This document also has shell scripts which provide simple commands to check-out, check-in, and commit files. See shell scripts at ``'' For RCS see the RCS mini-howto on the Linux cdrom: ______________________________________________________________________ cd /mnt/cdrom/Redhat/RPMS ls -l howto-6.0-*.noarch.rpm rpm -qpl howto-6* | grep -i rcs ______________________________________________________________________ or visit See also the RCS shell scripts at ``'' 3. Setting up CVS First you need to install the CVS package. On Redhat Linux use: ______________________________________________________________________ cd /mnt/cdrom/Redhat/RPMS rpm -i rcs*.rpm rpm -i cvs*.rpm To see the list of files installed do - rpm -qpl cvs*.rpm | less ______________________________________________________________________ and browse the output using j,k, CTRL+f, CTRL+D, CTRL+B, CTRL+U or using arrow keys, page up/down keys. See 'man less'. On other flavors of Unix, you may need to download the RCS and CVS tar balls and follow the README, INSTALL files to setup CVS. Visit and 3.1. Environment variables The following environment variables need to be setup in /etc/profile - default values required for all users. If not set in /etc/profile, then you should add these to your local profile file /.bash_profile. ______________________________________________________________________ export EDITOR=/bin/vi export CVSROOT=/home/cvsroot export CVSREAD=yes ______________________________________________________________________ Create a directory to store the source code repository and give read, write access to Unix group/user. Also make sure that the directory name of CVSROOT does not contain any blank spaces. For example CVSROOT should not be like '/home/my rootcvs'. ______________________________________________________________________ bash$ su - root bash# export CVSROOT=/home/cvsroot bash# groupadd --help bash# groupadd cvs bash# useradd --help bash# useradd -g cvs -d /home/cvsroot cvs bash# ls -ld $CVSROOT ... (you should see the listing) bash# chmod o-rwx $CVSROOT bash# chmod ug+rwx $CVSROOT #To initialize the CVS repository and to put in source code files do: bash# cvs init # Add the unix users to the cvs group. Create supplementary groups for users. # Note that you MUST not put any blank spaces after comma seperating the # group names in -G option. # In example below user tom belongs to groups cvs, users and staff and user # johnson belongs to group cvs only. bash# usermod --help bash# usermod -G cvs some_unix_username bash# usermod -G cvs,users,staff tom bash# usermod -G cvs,users,staroffice billclinton bash# usermod -G cvs johnson bash# exit .... (logout of root superuser mode) # Login as a user and import files into cvs.... bash$ su - billclinton bash$ export EDITOR=/bin/vi bash$ export CVSROOT=/home/cvsroot bash$ export CVSREAD=yes # Change directory is a must bash$ cd $HOME/my_source_code_dir # Must give vendor tag and revision tag cvs import my_source_code_dir Vendor1_0 Rev1_0 # For example I did: bash$ cd $HOME/foobar bash$ cvs import foobar Vendor1_0 Rev1_0 # A sample testing and verification: bash$ cd $HOME/foobar bash$ cvs checkout myfoo.java ______________________________________________________________________ TROUBLESHOOTING: When doing checkout it says module is unknown. It is a common mistake not to change directory while doing cvs import. You MUST change directory to the source-code-directory and then do cvs import. For example: ______________________________________________________________________ bash$ cd $HOME/foobardir bash$ cvs import foobardir Vendor1_0 Rev1_0 ______________________________________________________________________ 3.2. Migrate RCS to CVS To migrate the existing RCS files to CVS, use the following script. Make sure that you installed the Korn shell package pdksh*.rpm from the Linux contrib cdrom. NOTE : Get the Korn shell /bin/ksh by installing pdksh*.rpm from the Linux contrib cdrom ______________________________________________________________________ #!/bin/ksh ############################################################# # Program to Migrate the existing source code in RCS to CVS # # Needs the korn shell RPM package pdksh*.rpm from Linux # contrib cdrom ############################################################# # # rcs2cvs - convert source tree from RCS to CVS # # project to convert PROJECT='project' # current RCS root RCSROOT="$HOME/rcs" if cd "$RCSROOT/$PROJECT" then cd "$RCSROOT" else echo >&2 "`basename "$0"`: can't change to RCS directory '$RCSROOT/$PROJECT'." exit 1 fi # current CVS root CVSROOT="$HOME/cvs" # create new CVS directory for project 'project' if mkdir "$CVSROOT/$PROJECT" then : else echo >&2 "`basename "$0"`: can't create CVS directory '$CVSROOT/$PROJECT'." exit 2 fi # create CVS project tree from RCS tree find "$PROJECT" -type d -name RCS -print | while read RCS do CVS="`dirname "$RCS"`" (if cd "$RCS" then # if find . -type f -name '*,v' -print | cpio -pdmv "$CVSROOT/$CVS" if find . -type f -print | cpio -pdmv "$CVSROOT/$CVS" then : else echo >&2 "`basename "$0"`: can't convert RCS subdirectory '$RCSROOT/$RCS' to CVS subdirectory '$CVSROOT/$CVS'." fi else echo >&2 "`basename "$0"`: can't change to RCS subdirectory '$RCSROOT/$RCS'." fi) done ______________________________________________________________________ Now the RCS is migrated to CVS as 'project'. You can start using the CVS commands on module 'project'. 4. Intro to CVS Commands CVS provides a rich variety of commands (cvs_command in the Synopsis), each of which often has a wealth of options, to satisfy the many needs of source management in distributed environments. However, you don't have to master every detail to do useful work with CVS; in fact, five commands are sufficient to use (and contribute to) the source repository. The most commonly used CVS commands are: checkout, update, add, remove, commit and diff. 4.1. checkout cvs checkout modules... A necessary preliminary for most CVS work: creates your private copy of the source for modules (named collections of source; you can also use a path relative to the source repository here). You can work with this copy without interfering with others' work. At least one subdirectory level is always created. ______________________________________________________________________ bash$ cvs --help checkout Usage: cvs checkout [-ANPRcflnps] [-r rev | -D date] [-d dir] [-j rev1] [-j rev2] [-k kopt] modules... -A Reset any sticky tags/date/kopts. -N Don't shorten module paths if -d specified. -P Prune empty directories. -R Process directories recursively. -c "cat" the module database. -f Force a head revision match if tag/date not found. -l Local directory only, not recursive -n Do not run module program (if any). -p Check out files to standard output (avoids stickiness). -s Like -c, but include module status. -r rev Check out revision or tag. (implies -P) (is sticky) -D date Check out revisions as of date. (implies -P) (is sticky) -d dir Check out into dir instead of module name. -k kopt Use RCS kopt -k option on checkout. -j rev Merge in changes made between current revision and rev. (Specify the --help global option for a list of other help options) ______________________________________________________________________ 4.2. update cvs update Execute this command from within your private source directory when you wish to update your copies of source files from changes that other developers have made to the source in the repository. ______________________________________________________________________ bash$ cvs --help update Usage: cvs update [-APdflRp] [-k kopt] [-r rev|-D date] [-j rev] [-I ign] [-W spec] [files...] -A Reset any sticky tags/date/kopts. -P Prune empty directories. -d Build directories, like checkout does. -f Force a head revision match if tag/date not found. -l Local directory only, no recursion. -R Process directories recursively. -p Send updates to standard output (avoids stickiness). -k kopt Use RCS kopt -k option on checkout. -r rev Update using specified revision/tag (is sticky). -D date Set date to update from (is sticky). -j rev Merge in changes made between current revision and rev. -I ign More files to ignore (! to reset). -W spec Wrappers specification line. (Specify the --help global option for a list of other help options) ______________________________________________________________________ 4.3. add cvs add file... Use this command to enroll new files in CVS records of your working directory. The files will be added to the repository the next time you run `cvs commit'. Note: You should use the `cvs import' command to bootstrap new sources into the source repository. `cvs add' is only used for new files to an already checked-out module. ______________________________________________________________________ bash$ cvs --help add Usage: cvs add [-k rcs-kflag] [-m message] files... -k Use "rcs-kflag" to add the file with the specified kflag. -m Use "message" for the creation log. (Specify the --help global option for a list of other help options) ______________________________________________________________________ 4.4. remove cvs remove file... Use this command (after erasing any files listed) to declare that you wish to eliminate files from the repository. The removal does not affect others until you run `cvs commit'. ______________________________________________________________________ bash$ cvs --help remove Usage: cvs remove [-flR] [files...] -f Delete the file before removing it. -l Process this directory only (not recursive). -R Process directories recursively. (Specify the --help global option for a list of other help options) ______________________________________________________________________ 4.5. commit cvs commit file... Use this command when you wish to ``publish'' your changes to other developers, by incorporating them in the source repository. ______________________________________________________________________ bash$ cvs --help commit Usage: cvs commit [-nRlf] [-m msg | -F logfile] [-r rev] files... -n Do not run the module program (if any). -R Process directories recursively. -l Local directory only (not recursive). -f Force the file to be committed; disables recursion. -F file Read the log message from file. -m msg Log message. -r rev Commit to this branch or trunk revision. (Specify the --help global option for a list of other help options) ______________________________________________________________________ 4.6. diff cvs diff file... Show differences between files in the working directory and source repository, or between two revisions in the source repository. (Does not change either repository or working directory.) ______________________________________________________________________ bash$ cvs --help diff Usage: cvs diff [-lNR] [rcsdiff-options] [[-r rev1 | -D date1] [-r rev2 | -D date2]] [files...] -l Local directory only, not recursive -R Process directories recursively. -D d1 Diff revision for date against working file. -D d2 Diff rev1/date1 against date2. -N include diffs for added and removed files. -r rev1 Diff revision for rev1 against working file. -r rev2 Diff rev1/date1 against rev2. --ifdef=arg Output diffs in ifdef format. (consult the documentation for your diff program for rcsdiff-options. The most popular is -c for context diffs but there are many more). (Specify the --help global option for a list of other help options) ______________________________________________________________________ 4.7. Emacs Editor Emacs is a powerful editor and it supports CVS/RCS - especially for revision merging and comparing. The main Emacs site is at . 5. Strong, Weak or No Locking CVS is a powerful system and is highly customizable. CVS supports: · Strong locking with "reserved checkouts" via cvs admin -l or ``''. Also read the Reserved checkouts . Here is a patch ( ) from Eric Griswold for reserved checkouts. · Weak locking via 'cvs watch' features. Also see "cvs edit" to give a warning( ) if someone else is already editing the file. · No locking - the default permitting concurrent editing of files. 6. Shell Scripts The following are wrappers around the basic CVS commands. These scripts give you initial booster-push into the CVS system and are useful until you become very familiar with the CVS commands. The scripts are written for Korn shell since it is always available on all flavors of Unix, but you can translate to bash or Perl if needed. You can customize these scripts to your taste. They are basically CVS commands, but features are added to make it site specific. For example, the sedit script provides locking so that users will know someone is editing the file. Of course users can directly use the CVS commands to bypass these scripts. These scripts demonstrate how CVS can be customized to a great extent. NOTE: The wrapper shell scripts assume the user's home directory as the root and check out the tree from CVS to build the tree underneath user's home directory. TIP: In these shell scripts, every target filename is composed of 3 parts - Home directory, sub-directory and the filename. The full-path is $HOME/$subdir/$fname And in CVS the same directory structure is maintained (by variable $subdir) therefore in cvs there will be something like $CVSROOT/$subdir/$fname. In all scripts, these 4 variables $HOME, $CVSROOT, $subdir and $fname play an important role. For example, sample values can be like HOME=/home/aldev, subdir=myproject/src, CVSROOT=/home/cvsroot, and fname=foo.cpp Copy these scripts to /usr/local/bin and this should be in the user's PATH environment. 1. sget [-r revision_number] To get a file or entire directory from CVS in READ ONLY mode. Click ``'' 2. sedit [-r revision_number] To edit a file in order to make changes to code. This will lock the file so that nobody else can check it out. Of course you can change the script to your requirement - make no locking, warning message, or very strong locking. Click ``'' 3. scommit [-r revision_number] To commit the changes you made to filename or entire directory. Upload your changes to CVS. Click ``'' 4. supdate To update a filename or to update an entire directory by getting the latest files from CVS. Click ``'' 5. sunlock [-r revision_number] To unlock the file got by sedit. Will release the lock. Click ``'' 6. slist To see the list of files currently being edited by you. Does 'ls -l | grep | ...' command. Click ``''. Note that there is also another Unix command by the name slist (list available Netware servers). You should make sure cvs script slist comes before other in your PATH environment. 7. sinfo To get the information of changes/revisions to a file. Click ``'' 8. slog To get the history of changes/revisions to a file from CVS. Click ``'' 9. sdif sdif -r rev1 -r rev2 To get the diff of your file with CVS. Click ``'' NOTE: sdif has only one 'f' because there is already another Unix command called 'sdiff' 10. sadd To add a new file to CVS repository. Click ``'' 11. sdelete To delete a file from CVS repository. Click ``'' 12. sfreeze To freeze the code, that is make a release of the entire source tree. Click ``'' For example : ___________________________________________________________________ cd $HOME; sfreeze REVISION_1_0 srctree ___________________________________________________________________ This will freeze code with tag REVISION_1_0 so that you can later checkout the entire tree by using the revision name. ****************************************************** 7. CVS Documentation At Unix prompt type: 1. cvs --help 2. cvs --help-options 3. cvs --help-commands 4. cvs -H checkout 5. cvs -H commit 6. man cvs 7. man tkcvs 8. Visit 9. Visit The tkcvs is the Tcl/Tk GUI interface to CVS. It also has online help. Try the following: · cd $HOME/src/foo.cpp · tkcvs · Click on foo.cpp · Click on 'Revision Log Icon' which is located next to 'spectacle' icon. · This will display the branch TREE in the window. Now click the RIGHT Mouse button on the text '1.3' and click the LEFT Mouse button on text '1.1'. Then click on "Diff" button. This will display a two-pane window!! · Click on the "Next" button to step thru more diffs. Click on "Center" to center the text. There is also a Windows 95 client for CVS called WinCVS (see: and cyclicsite ). WinCVS can be used along with Samba(on cdrom samba*.rpm) - The essential command are: · cvs checkout · cvs update · cvs add · cvs remove · cvs commit · cvs status · cvs log · cvs diff -r1.4 -r1.5 This gives a diff between version 1.4 and 1.5 on filename. 7.1. Online Documentation On Linux systems, you can find the CVS documentation in postscript format at /usr/doc/cvs*/*.ps. Also there is an FAQ and other useful information. ______________________________________________________________________ bash# cd /usr/doc/cvs* bash# gv cvs.ps ______________________________________________________________________ 7.2. CVS Org Documentation The documentation on CVS from "CVS Organisation" is at The Official manual for CVS by Cederqvist is at FAQ for CVS is at 7.3. CVS Training · · · · · · General utilities for cvs (third party): · The textbook "Open Source Development with CVS" by Karl Fogel at has third-party-tools and mirror sites at Zevils · 8. Graphical Front Ends The following GUI front ends for CVS are available: · CVS home.org · CVS Web for windows and at · TkCVS is the Tcl/Tk GUI interface to CVS and at cyclicsite · gCVS: A portable GUI for the non-technical CVS user · jCVS is a CVS client package written entirely in Java And at cyclicsite · WinCVS and at cyclicsite · Component soft Win CVS · JA-SIG UPortal CVS · · It is very strongly recommended that you use Samba(on cdrom samba*.rpm) and a ``PC X Server'' on MS Windows 95/NT. By using Samba the remote directory on Unix will look like local folder on MS Windows. See the next section for ``PC X Server''. 9. CVS for MS Windows 95/98/NT/2000 It is VERY STRONGLY recommended that you use Samba(on cdrom samba*.rpm) and a VNC viewer (or PC X Server) on MS Windows 95/NT. With samba the Unix/Linux CVS server will be like a file server. By using Samba the remote directory on Unix will look like a local folder on MS Windows on the local disk. Install samba*.rpm on Unix/Linux server(which has the CVS repository) and install the VNC viewer (or PC X server) on MS Windows 95/NT/2000 desktop. Using a VNC (or PC X server) you can easily log on to the Unix box and check-out/check-in the files. And you can use tools like Java Visual Cafe or Java JBuilder on MS Windows to edit the files located in Unix/Linux folder(via samba). After editing, you can check-in the files to Unix through VNC or PC X-server. Advantages of using CVS on Linux/Unix via MS Windows are: · Only one single Linux File server (CVS server) can serve many MS Windows clients. · A Linux file server (CVS) is very robust, secure and reliable · Only one UPS (uninterrupted power supply) battery is required for a linux server. · Linux can serve as MS Windows folder through Samba package. · A Linux file server (CVS) supports centralised backups via tools like Arkeia, Bru mirrors at , angelfire , geocities , virtualave , 50megs , theglobe , NBCi , Terrashare , Fortunecity , Freewebsites , Tripod , Spree , Escalix , Httpcity , Freeservers . · A Linux file server (CVS) requires just one small server room which can air-contitioned and dust free. Small room keeps the cooling/heating costs down. · A Linux file server (CVS) provides security via Unix groups and user id authentication The best tool for remote access is VNC. The VNC is lightweight and is much better than the PC X servers. The VNC is very strongly recommended over PC X server. The remote access methods available are: · VNC (Virtual Network Computing) at VNC is not an X-server but can display the remote Unix on Windows. VNC is the best tool in the market for remote access, it is very lightweight and is a very powerful software. The following PC X servers are available: · Low cost, best and small size (3 MB) and click on "X-Server (MI/X) for Windows" · Humming bird eXceed 14 MB · Starnet 5.2 MB There are more than 2 dozen vendors for X servers for Windows: · X-win pro 6.34 MB · X-WinPro · X-Link · Xoftware University resources: · University listings · Floppy based PC "X server" 9.1. Windows 95/NT/2000 FTP Tools You can also use the ftp tools on MS Windows to transfer files from a Unix/Linux (CVS repository) to windows: · Go to Tucows and search "ftp tools" for MS Windows 9.2. Visual Cafe(Java), JBuilder, MS Visual C++, HTML files Using Samba and a PC X server it is possible to use CVS on MS Windows platform. And the tools like Symantec Visual Cafe (Java), Inprise JBuilder, MS Visual C++ and others are easily supported by CVS. You can also store the HTML files on a CVS repository via Samba and easily access them from MS Windows. 9.3. Samba Admin tool To administer samba use the admin tools from . Go here and click on "GUI Interfaces Tools". 10. Security of CVS Repository To make a CVS server and CVS repository secure do the following: · Run CVS on a stand-alone Linux/Unix box, see ``Performance Tuning''. · Remove unnecessary software packages from CVS linux box - to prevent external vandals running it. Just in case vandals break into the system, you do not want to give them a chance to run dangerous programs. · Consider SSH as given in the chapter ``Multi-User Repository'' · Consider Kerberos - install cvs-*-kerberos*.rpm package . · Visit and post your security questions in the mailing list . 11. Multi-User CVS Remote Repository The Cederqvist manual at describes how to setup CVS for external access. In order to use CVS for a group, one has to set up a permissions system to allow people to access the system from other machines. There are three ways to do this (:server:, :pserver:, and :ext:). The pserver mechanism and use of rsh are both insecure. Only the :ext: (with ssh) offers sufficient security protection. If you set CVS_RSH to SSH or some other rsh replacement, the instructions may be similar to `.rhosts' but consult the documentation for your rsh replacement. To get ssh visit and in the search box enter "ssh". Or visit and in the search box enter "ssh". Download and install the ssh RPM and then configure CVS to use it. See also . Note: If you plan to configure CVS for use with rsh then you MUST do this critical step: ______________________________________________________________________ bash# chmod 6000 .rhosts ______________________________________________________________________ See also JA-SIG UPortal CVS repository . 12. RCS Shell Scripts If you want to use RCS instead of CVS then you can use the following shell scripts. 12.1. cotree.sh ______________________________________________________________________ #!/bin/ksh # cotree.sh (Check Out Tree shell script) # cotree.sh - Check out the entire RCS directory # Usage : # This will get the all the directories # unix> cotree.sh # # This will get just one single directory tree # unix> cotree.sh # See also cofiles.sh ############################################################### # Setting up RCS (Revision Control System) # Install the RCS programs - which gives command co, ci, rcslog # Create a rcs home directory where you want to put all the # source code repository.

Performance Tuning of a CVS Server For optimum performance a CVS server must be running on a stand alone Linux/Unix box. To get more bang for a given CPU processing power, do the following: · Recompile the Linux kernel to make it small and lean. Remove items which are not used. See the kernel howto at · Turn off unneccessary Unix processes - on Linux/Unix systems run chkconfig. ___________________________________________________________________ bash$ su - root bash# man chkconfig bash# chkconfig --help bash# chkconfig --list | grep on | less From the above list, turn off the processes you do not want to start automatically - bash# chkconfig --level 0123456 off Next time when the machine is booted these services will not be started. Now, shutdown the services manually which you just turned off. bash# cd /etc/rc.d/init.d bash# ./ stop ___________________________________________________________________ · Do not run any other application processes which are unnecessary. · Do not leave X Window running unattended because its processes consume memory and contribute to CPU load. It can also be a serious security hole from outside attacks. The X Window managers generally used are KDE, GNOME, CDE, XDM and others. You must exit the X Window immediately after using and most of the time you should see a command line console login prompt on the CVS server machine. 14. Problem Reporting System Along with CVS, you may want to use project tracking system or problem reporting system. Every software project needs a problem reporting system that track bugs and assigns them to various developers. See GNU gpl GNATS at and And commercial PRS at look for a project tracking system. 15. Configuration Management System Tools What is Configuration Management (CM) ? There are a number of different interpretations. It is about the tracking and control of software development and its activities. That is, it concerns the mangement of software development projects with respect to issues such as multiple developers working on the same code at the same time, targeting multiple platforms, supporting multiple versions, and controlling the status of code (for example a beta test versus a real release). Even within that scope there are different schools of thought: · Traditional Configuration Management - checkin/checkout control of sources (and sometimes binaries) and the ability to perform builds (or compiles) of the entities. Other functions may be included as well. · Process Management - control of the software development activities. For example, it might check to ensure that a change request existed and had been approved for fixing and that the associated design, documentation, and review activities have been completed before allowing the code to be "checked in" again. While process management and control are necessary for a repeatable, optimized development process, a solid configuration management foundation for that process is essential.

SCCS v/s CVS-RCS SCCS (Source Code Control System) is no longer being enhanced or improved. The general consensus has been that this tool is clumsy and not suited to large numbers of users working on one project. Actually, SCCS interleaves all the versions, but it can make new development get progressively slower. Hence, SCCS is NOT recommended for new projects; however, it is still there to support old code base in SCCS. RCS (Revision Control System) is often considered to be better than SCCS. One reason for this is that RCS baselines the most recent version and keeps deltas for earlier ones, making new development faster. Additional discussions concerning SCCS vs RCS are at Note that RCS learned from the mistakes of SCCS... CVS, which requires RCS, extends RCS to control concurrent editing of sources by several users working on releases built from a hierarchical set of directories. "RCS is [analogous to using] assembly language, while CVS is [like using] Pascal". 18. Other Formats of this Document This document is published in 14 different formats namely: DVI, Postscript, Latex, Adobe Acrobat PDF, LyX, GNU-info, HTML, RTF(Rich Text Format), Plain-text, Unix man pages, single HTML file, SGML (Linuxdoc format), SGML (Docbook format), and MS WinHelp format. This howto document is located at: · and click on HOWTOs and search for the howto document name using CTRL+f or ALT+f within the web-browser. You can also find this document at the following mirrors sites: · · · · · Other mirror sites near you (network-address-wise) can be found at select a site and go to directory /LDP/HOWTO/xxxxx-HOWTO.html · You can get this HOWTO document as a single file tar ball in HTML, DVI, Postscript or SGML formats from - and · Plain text format is in: and · Single HTML file format is in: A single HTML file can be created with the command (see man sgml2html) - sgml2html -split 0 xxxxhowto.sgml · Translations to other languages like French, German, Spanish, Chinese, and Japanese are in and Any help from you to translate to other languages is welcome. The document is written using a tool called "SGML-Tools" which can be got from: Compiling the source you will get the following commands like: · sgml2html xxxxhowto.sgml (to generate html file) · sgml2html -split 0 xxxxhowto.sgml (to generate a single page html file) · sgml2rtf xxxxhowto.sgml (to generate RTF file) · sgml2latex xxxxhowto.sgml (to generate latex file) 18.1. Acrobat PDF format A PDF file can be generated from postscript file using either acrobat distill or Ghostscript. And a postscript file is generated from DVI which in turn is generated from a LaTex file. You can download distill software from . Given below is a sample session: ______________________________________________________________________ bash$ man sgml2latex bash$ sgml2latex filename.sgml bash$ man dvips bash$ dvips -o filename.ps filename.dvi bash$ distill filename.ps bash$ man ghostscript bash$ man ps2pdf bash$ ps2pdf input.ps output.pdf bash$ acroread output.pdf & ______________________________________________________________________ Or you can use the Ghostscript command ps2pdf. ps2pdf is a work-alike for nearly all the functionality of Adobe's Acrobat Distiller product: it converts PostScript files to Portable Document Format (PDF) files. ps2pdf is implemented as a very small command script (batch file) that invokes Ghostscript, selecting a special "output device" called pdfwrite. In order to use ps2pdf, the pdfwrite device must be included in the makefile when Ghostscript was compiled; see the documentation on building Ghostscript for details. 18.2. Convert Linuxdoc to Docbook format This document is written in linuxdoc SGML format. The Docbook SGML format supercedes the linuxdoc format and has a lot more features than linuxdoc. The linuxdoc is very simple and easy to use. To convert linuxdoc SGML file to Docbook SGML use the program ld2db.sh and some Perl scripts. The ld2db output is not 100% clean and you need to use the clean_ld2db.pl Perl script. You may need to manually correct a few lines in the document. · Download the ld2db program from or from Al Dev site · Download the cleanup_ld2db.pl perl script from from Al Dev site The ld2db.sh is not 100% clean, so you will get some errors when you run it. ___________________________________________________________________ bash$ ld2db.sh file-linuxdoc.sgml db.sgml bash$ cleanup.pl db.sgml > db_clean.sgml bash$ gvim db_clean.sgml bash$ docbook2html db.sgml ___________________________________________________________________ And you may have to manually edit some of the minor errors after run­ ning the Perl script. For example you may need to put closing tag < /Para> for each < Listitem> 18.3. Convert to MS WinHelp format You can convert the SGML howto document to a Microsoft Windows Help file, First convert the sgml to html using: ______________________________________________________________________ bash$ sgml2html xxxxhowto.sgml (to generate html file) bash$ sgml2html -split 0 xxxxhowto.sgml (to generate a single page html file) ______________________________________________________________________ Then use the tool HtmlToHlp . You can also use sgml2rtf and then use the RTF files for generating winhelp files. 18.4. Reading various formats In order to view the document in dvi format, use the xdvi program. The xdvi program is located in tetex-xdvi*.rpm package in Redhat Linux which can be located through ControlPanel | Applications | Publishing | TeX menu buttons. To read a dvi document give the command: xdvi -geometry 80x90 howto.dvi man xdvi And resize the window with the mouse. To navigate use Arrow keys, Page Up, Page Down keys, also you can use 'f', 'd', 'u', 'c', 'l', 'r', 'p', 'n' letter keys to move up, down, center, next page, previ­ ous page etc. To turn off expert menu press 'x'. You can read a postscript file using the program 'gv' (ghostview) or The ghostscript program is in the ghostscript*.rpm package and the gv program is in the gv*.rpm package in Redhat Linux which can be located through ControlPanel | Applications | Graphics menu buttons. The gv program is much more user friendly than ghostscript. Also ghostscript and gv are available on other platforms like OS/2, Windows 95 and NT. You can view this document even on those platforms. · Get ghostscript for Windows 95, OS/2, and for all OSes from To read a postscript document give the command: gv howto.ps ghostscript howto.ps You can read an HTML format document using Netscape Navigator, Microsoft Internet explorer, Redhat Baron Web browser or any of the 10 other web browsers. You can read the latex, LyX output using LyX an X Window front end to LaTex. 19. Copyright and License Copyright Al Dev (Alavoor Vasudevan) 1998-2000.
