 =head2 Handling of pmc files
 
-TODO XXX explain what are pmc files
+And old feature of perl is that before C<require> or C<use> look for a
+file with a F<.pm> extension, they will first look for a similar filename
+with a F<.pmc> extension. If this file is found, it will be loaded in
+place of any potentially existing file ending in a F<.pm> extension.
 
-.pmc files are always loaded, even if they are older than a matching .pm
-file. (This trick is used by Pugs.)
+Previously, F<.pmc> files were loaded only if more recent than the
+matching F<.pm> file. Starting with 5.9.4, they'll be always loaded if
+they exist. (This trick is used by Pugs.)
