This message contains a shar wrapping of the following files:
$ crc *
23828 3238 out.h
This include file describes the ACK object file format.
Go to an empty directory, feed the lines following the cut mark
to the shell, check the table above with the output of /usr/bin/crc
and install as follows:
$ cp * /usr/include
Good luck.
