+RelPath
+=======
+
+RelPath is a small PHP library for computing a relative filepath to some path,
+either from the current directory or from an optional start directory.
+
+Here is how you use it:
+
+<pre lang="php">
+$relPath = RelPath\getRelativePath( '/srv/mediawiki/resources/src/startup.js', '/srv/mediawiki' );
+// Result: string(24) "resources/src/startup.js"
+
+$fullPath = RelPath\joinPath( '/srv/mediawiki', 'resources/src/startup.js' );
+// Result: string(39) "/srv/mediawiki/resources/src/startup.js"
+</pre>
