Note:
To create space, some .ARC files were compressed. The decompress
utility can be built using the files in [5,14]lzpdp11.arc using
the procedure documented therein. This was necessary to get the
tape to a reasonable size.
Compressed files are flagged by Z as the 2nd character of
the filetype (e.g. ESA.AZC resulted from ESA.ARC).
