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 subdirectory of $CVSROOT.

The files described here are supporting files; they do not have to exist for cvs to
operate, but they allow 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 execute. These programs are used for ``pre-commit'' checking to verify that the
modified, added, and removed 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 message to a particular newsgroup.

You can use the `taginfo' file to define programs to execute after any tagorrtag
operation. These programs 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/CVSROOT/modules,v'.

The `modules' file may contain blank lines and comments (lines beginning with `#')
as well as module 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 directory, 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.

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 repository. 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 whitespace 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 # character, 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 include not only a program name, but whatever list of arguments you
wish. If you write `%s' somewhere 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 exit 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 involved 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 include not only a program name, but whatever list of arguments you
wish. The full path to the current 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 expression, 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 information 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 article 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 history').
