# Slackware build script for crc32_simple

# Why doesn't Slackware already have some tool that can do crc32?
|
|
# There are TCL and PHP modules, the kernel includes its own crc32 algo,
|
|
# but nothing you can run directly from the command line.
|
|
|
|
# VERSION is from the timestamp on the source file.
