-
-Takes a destination path and an optional base path returns a relative path
-from the base path to the destination path:
-
- $rel_path = File::Spec->abs2rel( $destination ) ;
- $rel_path = File::Spec->abs2rel( $destination, $base ) ;
-
-If $base is not present or '', then L</cwd()> is used. If $base is relative,
-then it is converted to absolute form using L</rel2abs()>. This means that it
-is taken to be relative to L<cwd()>.
-
-On systems with the concept of a volume, this assumes that both paths
-are on the $destination volume, and ignores the $base volume.
-
-On systems that have a grammar that indicates filenames, this ignores the
-$base filename as well. Otherwise all path components are assumed to be
-directories.
-
-If $path is relative, it is converted to absolute form using L</rel2abs()>.
-This means that it is taken to be relative to L</cwd()>.
-
-Based on code written by Shigio Yamaguchi.

-No checks against the filesystem are made.
