Subject: [*] dataThief v1.0.6

DataThief v1.0.6 is an application  to read data from a (scanned)
graph. It reads both PICT and  Paint files and converts the lines
on an  X-Y graph  back in  the numbers  that originally  made the
graph. It has both an auto-trace and a manual mode.

It's system 7 compatible PostCardware.
