GtkBlowIT (a.k.a GNU BlowIt) is programming software for a very simple,
easy-to-build device (programmer) with which you can program AT89C2051 (MCS-51
compatible) microcontrollers.

Filesize is now checked, and the effective user ID is checked (fixes a segfault). Schematics for the programmer and some documentation have been added. The default port has been changed to 0x378. There are other minor enhancements.
