+FILTER API
+----------
+- 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 )
+
+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.
