[GRASS-dev] Re: [GRASS-user] r.reclass not spawning xterm on Mac OS X

[Michael Barton]

Am I understanding the proposed changes correctly? They will make no
difference for how the current wrapper scripts operate with r.reclass (and
related files), but will will make them functional--albeit in the old xterm
interface--when run from the command line without arguments. This will serve
as an interim solution for keeping these modules functional while the old
interactive xterm modules are being phased out.

Is this the gist or did I miss an important point?

Michael
