olf

UNIX下FILE命令的实现源码

#------------------------------------------------------------------------------
# olf:  file(1) magic for OLF executables
#
# We have to check the byte order flag to see what byte order all the
# other stuff in the header is in.
#
# MIPS R3000 may also be for MIPS R2000.
# What're the correct byte orders for the nCUBE and the Fujitsu VPP500?
