# a.out2com - Minix a.out to DOS .COM Author: Kees J. Bot
# 17 Jun 1995
# Transform a Minix a.out to the COM format of MS-DOS,
# the executable must be common I&D with 256 scratch bytes at the start of
# the text segment to make space for the Program Segment Prefix. The Minix
# a.out header and these 256 bytes are removed to make a COM file.
