Here is a suggestion so protocols can be grouped together under libpurple.
<OPTIONS_DEFINE=BONJOUR DBUS GNUTLS NSS SASL GSTREAMER VV IDN PERL TCLTK \
< SAMETIME SILC GG IRC JABBER MSN MYSPACE NOVELL OSCAR QQ \
< SIMPLE YAHOO ZEPHYR
> OPTIONS_DEFINE= DBUS GNUTLS NSS SASL GSTREAMER VV IDN PERL TCLTK
> OPTIONS_GROUP= PROTOCOLS
> OPTIONS_GROUP_PROTOCOLS= BONJOUR GG SAMETIME SILC IRC JABBER MSN MYSPACE \
> NOVELL OSCAR QQ SIMPLE YAHOO ZEPHYR
Bonjour acts like a protocol as well. The options were moved from define, into their own protocol group. It works the same, as the descriptions are already made.
I've emailed the maintainer about a week ago, and there's even a request on the ports mailing list, but there hasn't been a response. This is to make it easier to configure options for Pidgin, Finch and libpurple. Thank you.
