linking to gnome uri handlers from general script

[Jose M Rodriguez]

Hi again,

Working on mozilla apps general integration with FreeBSD and need to 
solve two basic questions.

An env detect method to HiFi detect that a sh app is running from 
gnome-session. (An env var set only when gnome-session is running).

A sh exec method to open a generic uri in the default handler set by the 
control-center ( prefered apps / mime types ).

thanks in advance,
