+libpkgconf `fragment` module
+============================
+
+The `fragment` module provides low-level management and rendering of fragment lists.  A
+`fragment list` contains various `fragments` of text (such as ``-I /usr/include``) in a matter
+which is composable, mergeable and reorderable.
+
+.. c:function:: void pkgconf_fragment_add(const pkgconf_client_t *client, pkgconf_list_t *list, const char *string)
+
+   Adds a `fragment` of text to a `fragment list`, possibly modifying the fragment if a sysroot is set.
+
+   :param pkgconf_client_t* client: The pkgconf client being accessed.
+   :param pkgconf_list_t* list: The fragment list.
+   :param char* string: The string of text to add as a fragment to the fragment list.
+   :return: nothing
+
+.. c:function:: bool pkgconf_fragment_has_system_dir(const pkgconf_client_t *client, const pkgconf_fragment_t *frag)
+
+   Checks if a `fragment` contains a `system path`.  System paths are detected at compile time and optionally overridden by
+   the ``PKG_CONFIG_SYSTEM_INCLUDE_PATH`` and ``PKG_CONFIG_SYSTEM_LIBRARY_PATH`` environment variables.
+
+   :param pkgconf_client_t* client: The pkgconf client object the fragment belongs to.
+   :param pkgconf_fragment_t* frag: The fragment being checked.
+   :return: true if the fragment contains a system path, else false
+   :rtype: bool
+
+.. c:function:: void pkgconf_fragment_copy(const pkgconf_client_t *client, pkgconf_list_t *list, const pkgconf_fragment_t *base, bool is_private)
+
+   Copies a `fragment` to another `fragment list`, possibly removing a previous copy of the `fragment`
+   in a process known as `mergeback`.
+
+   :param pkgconf_client_t* client: The pkgconf client being accessed.
+   :param pkgconf_list_t* list: The list the fragment is being added to.
+   :param pkgconf_fragment_t* base: The fragment being copied.
+   :param bool is_private: Whether the fragment list is a `private` fragment list (static linking).
+   :return: nothing
+
+.. c:function:: void pkgconf_fragment_filter(const pkgconf_client_t *client, pkgconf_list_t *dest, pkgconf_list_t *src, pkgconf_fragment_filter_func_t filter_func)
+
+   Copies a `fragment list` to another `fragment list` which match a user-specified filtering function.
+
+   :param pkgconf_client_t* client: The pkgconf client being accessed.
+   :param pkgconf_list_t* dest: The destination list.
+   :param pkgconf_list_t* src: The source list.
+   :param pkgconf_fragment_filter_func_t filter_func: The filter function to use.
+   :param void* data: Optional data to pass to the filter function.
+   :return: nothing
+
+.. c:function:: size_t pkgconf_fragment_render_len(const pkgconf_list_t *list)
+
+   Calculates the required memory to store a `fragment list` when rendered as a string.
+
+   :param pkgconf_list_t* list: The `fragment list` being rendered.
+   :param bool escape: Whether or not to escape special shell characters.
+   :return: the amount of bytes required to represent the `fragment list` when rendered
+   :rtype: size_t
+
+.. c:function:: void pkgconf_fragment_render_buf(const pkgconf_list_t *list, char *buf, size_t buflen)
+
+   Renders a `fragment list` into a buffer.
+
+   :param pkgconf_list_t* list: The `fragment list` being rendered.
+   :param char* buf: The buffer to render the fragment list into.
+   :param size_t buflen: The length of the buffer.
+   :param bool escape: Whether or not to escape special shell characters.
+   :return: nothing
+
+.. c:function:: char *pkgconf_fragment_render(const pkgconf_list_t *list)
+
+   Allocate memory and render a `fragment list` into it.
+
+   :param pkgconf_list_t* list: The `fragment list` being rendered.
+   :param bool escape: Whether or not to escape special shell characters.
+   :return: An allocated string containing the rendered `fragment list`.
+   :rtype: char *
+
+.. c:function:: void pkgconf_fragment_delete(pkgconf_list_t *list, pkgconf_fragment_t *node)
+
+   Delete a `fragment node` from a `fragment list`.
+
+   :param pkgconf_list_t* list: The `fragment list` to delete from.
+   :param pkgconf_fragment_t* node: The `fragment node` to delete.
+   :return: nothing
+
+.. c:function:: void pkgconf_fragment_free(pkgconf_list_t *list)
+
+   Delete an entire `fragment list`.
+
+   :param pkgconf_list_t* list: The `fragment list` to delete.
+   :return: nothing
+
+.. c:function:: bool pkgconf_fragment_parse(const pkgconf_client_t *client, pkgconf_list_t *list, pkgconf_list_t *vars, const char *value)
+
+   Parse a string into a `fragment list`.
+
+   :param pkgconf_client_t* client: The pkgconf client being accessed.
+   :param pkgconf_list_t* list: The `fragment list` to add the fragment entries to.
+   :param pkgconf_list_t* vars: A list of variables to use for variable substitution.
+   :param char* value: The string to parse into fragments.
+   :return: true on success, false on parse error
