srccrc - compute CRC checksums of the entire source tree
Srccrc traverses the entire /usr/include and /usr/src tree to run the crc
command on all files found. The result is a long list of filenames with
their checksums. The filenames are relative to /usr.
The command makes an effort to remove most junk files such as .o, .bak
and files in bin directories. It cannot find single binaries however, so
you will have to run make clean in /usr/src to be able to make a crc list
that contains only source files.
Two crc files can be compared easily with the diff command. A crc list
of the original source tree can be found in /usr/src/crclist.
