## The commit support files

The ``-i'` flag in the ``modules'` file can be used to run a certain program whenever files are committed (see section The modules file). The files described in this section provide other, more flexible, ways to run programs whenever something is committed.

There are three kind of programs that can be run on commit. They are specified in files in the repository, as described below. The following table summarizes the file names and the purpose of the corresponding programs.

``commitinfo'`
  The program is responsible for checking that the commit is allowed. If it exits with a non-zero exit status the commit will be aborted.
``editinfo'`
  The specified program is used to edit the log message, and possibly verify that it contains all required fields. This is most useful in combination with the ``rcsinfo'` file, which can hold a log message template (see section Rcsinfo).
``loginfo'`
  The specified program is called when the commit is complete. It receives the log message and some additional information and can store the log message in a file, or mail it to appropriate persons, or maybe post it to a local newsgroup, or... Your imagination is the limit!
