+libpkgconf `path` module
+========================
+
+The `path` module provides functions for manipulating lists of paths in a cross-platform manner.  Notably,
+it is used by the `pkgconf client` to parse the ``PKG_CONFIG_PATH``, ``PKG_CONFIG_LIBDIR`` and related environment
+variables.
+
+.. c:function:: void pkgconf_path_add(const char *text, pkgconf_list_t *dirlist)
+
+   Adds a path node to a path list.  If the path is already in the list, do nothing.
+
+   :param char* text: The path text to add as a path node.
+   :param pkgconf_list_t* dirlist: The path list to add the path node to.
+   :param bool filter: Whether to perform duplicate filtering.
+   :return: nothing
+
+.. c:function:: size_t pkgconf_path_split(const char *text, pkgconf_list_t *dirlist)
+
+   Splits a given text input and inserts paths into a path list.
+
+   :param char* text: The path text to split and add as path nodes.
+   :param pkgconf_list_t* dirlist: The path list to have the path nodes added to.
+   :param bool filter: Whether to perform duplicate filtering.
+   :return: number of path nodes added to the path list
+   :rtype: size_t
+
+.. c:function:: size_t pkgconf_path_build_from_environ(const char *environ, const char *fallback, pkgconf_list_t *dirlist)
+
+   Adds the paths specified in an environment variable to a path list.  If the environment variable is not set,
+   an optional default set of paths is added.
+
+   :param char* environ: The environment variable to look up.
+   :param char* fallback: The fallback paths to use if the environment variable is not set.
+   :param pkgconf_list_t* dirlist: The path list to add the path nodes to.
+   :param bool filter: Whether to perform duplicate filtering.
+   :return: number of path nodes added to the path list
+   :rtype: size_t
+
+.. c:function:: bool pkgconf_path_match_list(const char *path, const pkgconf_list_t *dirlist)
+
+   Checks whether a path has a matching prefix in a path list.
+
+   :param char* path: The path to check against a path list.
+   :param pkgconf_list_t* dirlist: The path list to check the path against.
+   :return: true if the path list has a matching prefix, otherwise false
+   :rtype: bool
+
+.. c:function:: void pkgconf_path_free(pkgconf_list_t *dirlist)
+
+   Releases any path nodes attached to the given path list.
+
+   :param pkgconf_list_t* dirlist: The path list to clean up.
+   :return: nothing
+
+.. c:function:: bool pkgconf_path_relocate(char *buf, size_t buflen)
+
+   Relocates a path, possibly calling normpath() or cygwin_conv_path() on it.
+
+   :param char* buf: The path to relocate.
+   :param size_t buflen: The buffer length the path is contained in.
+   :return: true on success, false on error
+   :rtype: bool
