# Descr.:  Little GTK+ enabled Perl script for adding ed2k:// links to     #
#          ed2k GUI, designed for better ed2k:// URL handling within Gnome #
#          (especially Galeon) but might be used for any other purpose.    #
#                                                                          #
# Syntax:  ed2k_urlslave <ed2k:// url>                                     #
############################################################################
# Setting up ed2k_urlslave and Gnome:                                      #
# 1. Copy ed2k_urlslave to a place in $PATH, I suggest /usr/local/bin/     #
# 2. Start gnomecc and open the URL handler capplet                        #
# 3. Fill 'ed2k' into the protocol field and 'ed2k_urlslave "%s"' to the   #
#    handler field                                                         #
# 4. Hit 'set' to add the new protocol handler to the list                 #
# 5. Take any Gnome program (e.g. Galeon) and click some ed2k:// URLs ;)   #
