 * 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.
