how does it break devel installations? it resides only in the source directory and is not copied by the SConscript..
i haven't been able to figure that out, yet ... my guess is that if pd is run from a specific directory, it finds your pd.tk, not the pd.tk from u_main.tk ... some people run pd, without installing it!
you can go ahead and delete it, since every time ive ever checked in somethign to devel, it got overwritten eventually, either by a checkin from yourself...or a version rev of the devel tag, or a version rev from miller which didnt take any of the stuff from devel anyways...so its a fairly pointless exercise, except that i like to have a remote backup of my stuff somewhere reliable..
i can understand you ... but i'm trying to maintain the stuff and i'm the one that people contact when "devel doesn't work" or "i can't see a menu" or "devel_0_39: wont launch (bug)"
i'm happy for any contribution to devel, but i think i've given you reasons, why i rejected the ix-gui, why i have problems with the pd.tk, any with yesterday's change to the sconscript ...
cheer ... tim
