       Available functions
       ------------------------------------------------------------
       
       extension_equals(string: extension)
       ------------------------------------
       
       Tests if the extension of the found file equals extension.
       
         $ efind . 'extension_equals(".txt") or extension_equals(".TXT")'
       
       
       extension_equals(string: extension)
       -----------------------------------
       
       Tests if the extension of the found file equals extension.
       The string comparison is case in-sensitive.
       
         $ efind . 'extension_equals_icase(".TxT")'
       
       
       extension_in(string: extensions)
       --------------------------------
       
       Tests if the comma-separated list extensions contains the
       file extension of the found file.
       
         $ efind . 'extension_in(".c, .h")'
       
       
       extension_in_icase(string: extensions)
       --------------------------------------
       
       Tests if the comma-separated list extensions contains the
