+
+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 (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.
