+/**
+ * \mainpage PhysicsFS globbing
+ *
+ * This is an extension to PhysicsFS to let you search for files with basic
+ *  wildcard matching, regardless of what sort of filesystem or archive they
+ *  reside in. It does this by enumerating directories as needed and manually
+ *  locating matching entries.
+ *
+ * Usage: Set up PhysicsFS as you normally would, then use
+ *  PHYSFSEXT_enumerateFilesPattern() when enumerating files. This is just
+ *  like PHYSFS_enumerateFiles(), but it returns a subset that matches your
+ *  wildcard pattern. You must call PHYSFS_freeList() on the results, just
+ *  like you would with PHYSFS_enumerateFiles().
+ *
+ * License: this code is public domain. I make no warranty that it is useful,
+ *  correct, harmless, or environmentally safe.
+ *
+ * This particular file may be used however you like, including copying it
+ *  verbatim into a closed-source project, exploiting it commercially, and
+ *  removing any trace of my name from the source (although I hope you won't
+ *  do that). I welcome enhancements and corrections to this file, but I do
+ *  not require you to send me patches if you make changes.
+ *
+ * Unless otherwise stated, the rest of PhysicsFS falls under the GNU Lesser
+ *  General Public License: http://www.gnu.org/licenses/lgpl.txt

+/**
+ * \fn char **PHYSFS_enumerateFilesWildcard(const char *dir, const char *wildcard, int caseSensitive)
+ * \brief Get a file listing of a search path's directory.
+ *
+ * Matching directories are interpolated. That is, if "C:\mydir" is in the
+ *  search path and contains a directory "savegames" that contains "x.sav",
+ *  "y.Sav", and "z.txt", and there is also a "C:\userdir" in the search path
+ *  that has a "savegames" subdirectory with "w.sav", then the following code:
+ *
+ * \code
+ * char **rc = PHYSFS_enumerateFilesWildcard("savegames", "*.sav", 0);
+ * char **i;
+ *
+ * for (i = rc; *i != NULL; i++)
+ *     printf(" * We've got [%s].\n", *i);
+ *
+ * PHYSFS_freeList(rc);
+ * \endcode
+ *
+ *  ...will print:
+ *
+ * \verbatim
+ * We've got [x.sav].
+ * We've got [y.Sav].
+ * We've got [w.sav].\endverbatim
+ *
+ * Feel free to sort the list however you like. We only promise there will
+ *  be no duplicates, but not what order the final list will come back in.
+ *
+ * Wildcard strings can use the '*' and '?' characters, currently.
+ * Matches can be case-insensitive if you pass a zero for argument 3.
+ *
+ * Don't forget to call PHYSFS_freeList() with the return value from this
+ *  function when you are done with it.
+ *
+ *    \param dir directory in platform-independent notation to enumerate.
+ *   \return Null-terminated array of null-terminated strings.
