-- about filter::
-  This filter is given no arguments.
-  The about text that is to be filtered is available on standard input and the
-  filtered text is expected on standard output.
-- commit filter::
-  This filter is given no arguments.
-  The commit message text that is to be filtered is available on standard input
-  and the filtered text is expected on standard output.
-- source filter::
-  This filter is given a single parameter: the filename of the source file to
-  filter. The filter can use the filename to determine (for example) the syntax
-  highlighting mode.
-  The contents of the source file that is to be filtered is available on
-  standard input and the filtered contents is expected on standard output.

 Also, all filters are handed the following environment variables:
-- CGIT_REPO_URL        ( = repo.url       setting )
-- CGIT_REPO_NAME       ( = repo.name      setting )
-- CGIT_REPO_PATH       ( = repo.path      setting )
-- CGIT_REPO_OWNER      ( = repo.owner     setting )
-- CGIT_REPO_DEFBRANCH  ( = repo.defbranch setting )
-- CGIT_REPO_SECTION    ( = section        setting )
-- CGIT_REPO_CLONE_URL  ( = repo.clone-url setting )

+- CGIT_REPO_URL (from repo.url)
+- CGIT_REPO_NAME (from repo.name)
+- CGIT_REPO_PATH (from repo.path)
+- CGIT_REPO_OWNER (from repo.owner)
+- CGIT_REPO_DEFBRANCH (from repo.defbranch)
+- CGIT_REPO_SECTION (from repo.section)
+- CGIT_REPO_CLONE_URL (from repo.clone-url)
 
 If a setting is not defined for a repository and the corresponding global
 setting is also not defined (if applicable), then the corresponding
 environment variable will be an empty string.
 
-Note that under normal circumstance all these environment variables are
-defined. If however the total size of the defined settings exceed the
-allocated buffer within cgit then only the environment variables that fit
-in the allocated buffer are handed to the filter.
