Subject: Boiler-plate code for opening/saving a file
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;ds=sidebyside;h=3d01a5f71a29a8b7ce2a3648130660dabe62fae9;p=ext%2Fsubsurface.git

Boiler-plate code for opening/saving a file

All just copied from the gtk docs.  No actual loading or saving is
taking place, though.
