|
|
|
32 These tests compress the contents of a file specified on the command line, writing
|
|
|
33 the compressed data to v42bis_tests.v42bis. They then read back the contents of the
|
|
|
34 compressed file, decompress, and write the results to v42bis_tests.out. The contents
|
|
|
35 of this file should exactly match the original file.
