DESCRIPTION

cvs is a system for providing source control to hierarchical collections of source directories. Commands
and procedures for using cvs are described in cvs(1).

cvs manages source repositories, the directories containing master copies of the revision-controlled
files, by copying particular revisions of the files to (and modifications back from) developers' private
working directories. In terms of file structure, each individual source repository is an immediate sub‐
directory of $CVSROOT.

The files described here are supporting files; they do not have to exist for cvs to operate, but they al‐
low you to make cvs operation more flexible.

You can use the `modules' file to define symbolic names for collections of source maintained with cvs.
If there is no `modules' file, developers must specify complete path names (absolute, or relative to
$CVSROOT) for the files they wish to manage with cvs commands.

You can use the `commitinfo' file to define programs to execute whenever `cvs commit' is about to exe‐
cute. These programs are used for ``pre-commit'' checking to verify that the modified, added, and re‐
moved files are really ready to be committed. Some uses for this check might be to turn off a portion
(or all) of the source repository from a particular person or group. Or, perhaps, to verify that the
changed files conform to the site's standards for coding practice.

You can use the `cvswrappers' file to record cvs wrapper commands to be used when checking files into and
out of the repository. Wrappers allow the file or directory to be processed on the way in and out of
CVS. The intended uses are many, one possible use would be to reformat a C file before the file is
checked in, so all of the code in the repository looks the same.

You can use the `loginfo' file to define programs to execute after any commit, which writes a log entry
for changes in the repository. These logging programs might be used to append the log message to a file.
Or send the log message through electronic mail to a group of developers. Or, perhaps, post the log mes‐
sage to a particular newsgroup.

You can use the `taginfo' file to define programs to execute after any tagorrtag operation. These pro‐
grams might be used to append a message to a file listing the new tag name and the programmer who created
it, or send mail to a group of developers, or, perhaps, post a message to a particular newsgroup.

You can use the `rcsinfo' file to define forms for log messages.

You can use the `editinfo' file to define a program to execute for editing/validating `cvs commit' log
entries. This is most useful when used with a `rcsinfo' forms specification, as it can verify that the
proper fields of the form have been filled in by the user committing the change.

You can use the `cvsignore' file to specify the default list of files to ignore during update.

You can use the `history' file to record the cvs commands that affect the repository. The creation of
this file enables history logging.

FILES

modules
The `modules' file records your definitions of names for collections of source code. cvs will use
these definitions if you use cvs to check in a file with the right format to `$CVSROOT/CVS‐
ROOT/modules,v'.

The `modules' file may contain blank lines and comments (lines beginning with `#') as well as mod‐
ule definitions. Long lines can be continued on the next line by specifying a backslash (``\'')
as the last character on the line.

A module definition is a single line of the `modules' file, in either of two formats. In both
cases, mname represents the symbolic module name, and the remainder of the line is its definition.

mname -a aliases...
This represents the simplest way of defining a module mname. The `-a' flags the definition as a
simple alias: cvs will treat any use of mname (as a command argument) as if the list of names
aliases had been specified instead. aliases may contain either other module names or paths. When
you use paths in aliases, `cvs checkout' creates all intermediate directories in the working di‐
rectory, just as if the path had been specified explicitly in the cvs arguments.

mname [ options ] dir [ files... ] [ &module... ]

In the simplest case, this form of module definition reduces to `mname dir'. This defines all the
files in directory dir as module mname. dir is a relative path (from $CVSROOT) to a directory of
source in one of the source repositories. In this case, on checkout, a single directory called
mname is created as a working directory; no intermediate directory levels are used by default,
even if dir was a path involving several directory levels.

By explicitly specifying files in the module definition after dir, you can select particular files
from directory dir. The sample definition for modules is an example of a module defined with a
single file from a particular directory. Here is another example:

m4test unsupported/gnu/m4 foreach.m4 forloop.m4

With this definition, executing `cvs checkout m4test' will create a single working directory
`m4test' containing the two files listed, which both come from a common directory several levels
deep in the cvs source repository.

A module definition can refer to other modules by including `&module' in its definition. checkout
creates a subdirectory for each such module, in your working directory.
New in cvs 1.3; avoid this feature if sharing module definitions with older versions of cvs.

Finally, you can use one or more of the following options in module definitions:

`-d name', to name the working directory something other than the module name.
New in cvs 1.3; avoid this feature if sharing module definitions with older versions of cvs.

`-i prog' allows you to specify a program prog to run whenever files in a module are committed.
prog runs with a single argument, the full pathname of the affected directory in a source reposi‐
tory. The `commitinfo', `loginfo', and `editinfo' files provide other ways to call a program on
commit.

`-o prog' allows you to specify a program prog to run whenever files in a module are checked out.
prog runs with a single argument, the module name.

`-e prog' allows you to specify a program prog to run whenever files in a module are exported.
prog runs with a single argument, the module name.

`-t prog' allows you to specify a program prog to run whenever files in a module are tagged. prog
runs with two arguments: the module name and the symbolic tag specified to rtag.

`-u prog' allows you to specify a program prog to run whenever `cvs update' is executed from the
top-level directory of the checked-out module. prog runs with a single argument, the full path to
the source repository for this module.

commitinfo, loginfo, rcsinfo, editinfo
These files all specify programs to call at different points in the `cvs commit' process. They
have a common structure. Each line is a pair of fields: a regular expression, separated by white‐
space from a filename or command-line template. Whenever one of the regular expression matches a
directory name in the repository, the rest of the line is used. If the line begins with a # char‐
acter, the entire line is considered a comment and is ignored. Whitespace between the fields is
also ignored.

For `loginfo', the rest of the line is a command-line template to execute. The templates can in‐
clude not only a program name, but whatever list of arguments you wish. If you write `%s' some‐
where on the argument list, cvs supplies, at that point, the list of files affected by the commit.
The first entry in the list is the relative path within the source repository where the change is
being made. The remaining arguments list the files that are being modified, added, or removed by
this commit invocation.

For `taginfo', the rest of the line is a command-line template to execute. The arguments passed
to the command are, in order, the tagname , operation (i.e. add for `tag', mov for `tag -F', and
del for `tag -d`), repository , and any remaining are pairs of filename revision . A non-zero ex‐
it of the filter program will cause the tag to be aborted.

For `commitinfo', the rest of the line is a command-line template to execute. The template can
include not only a program name, but whatever list of arguments you wish. The full path to the
current source repository is appended to the template, followed by the file names of any files in‐
volved in the commit (added, removed, and modified files).

For `rcsinfo', the rest of the line is the full path to a file that should be loaded into the log
message template.

For `editinfo', the rest of the line is a command-line template to execute. The template can in‐
clude not only a program name, but whatever list of arguments you wish. The full path to the cur‐
rent log message template file is appended to the template.

You can use one of two special strings instead of a regular expression: `ALL' specifies a command
line template that must always be executed, and `DEFAULT' specifies a command line template to use
if no regular expression is a match.

The `commitinfo' file contains commands to execute before any other commit activity, to allow you
to check any conditions that must be satisfied before commit can proceed. The rest of the commit
will execute only if all selected commands from this file exit with exit status 0.

The `rcsinfo' file allows you to specify log templates for the commit logging session; you can use
this to provide a form to edit when filling out the commit log. The field after the regular ex‐
pression, in this file, contains filenames (of files containing the logging forms) rather than
command templates.

The `editinfo' file allows you to execute a script before the commit starts, but after the log in‐
formation is recorded. These "edit" scripts can verify information recorded in the log file. If
the edit script exits with a non-zero exit status, the commit is aborted.

The `loginfo' file contains commands to execute at the end of a commit. The text specified as a
commit log message is piped through the command; typical uses include sending mail, filing an ar‐
ticle in a newsgroup, or appending to a central file.

cvsignore, .cvsignore
The default list of files (or sh(1) file name patterns) to ignore during `cvs update'. At startup
time, cvs loads the compiled in default list of file name patterns (see cvs(1)). Then the per-
repository list included in $CVSROOT/CVSROOT/cvsignore is loaded, if it exists. Then the per-user
list is loaded from `$HOME/.cvsignore'. Finally, as cvs traverses through your directories, it
will load any per-directory `.cvsignore' files whenever it finds one. These per-directory files
are only valid for exactly the directory that contains them, not for any sub-directories.

history
Create this file in $CVSROOT/CVSROOT to enable history logging (see the description of `cvs histo‐
ry').
