LZH File Format
In case you wonder why these archives are in LZH format, which is
not very popular on CP/M, here is why:
- The LBR file format looks a bit unwieldy, and I do not know any
good Unix program for managing these.
- The ARC or ARK file format is supposed to be compatible between Unix
and CP/M, but I tried it and ARK (on CP/M) cannot decode ARC (Unix) files
and vice versa. Probably due to incompatible compression methods.
Interestingly, this happens even when telling Unix ARC to squash files.
- LZH files are much smaller than ARC files and a CP/M program exists
to extract archives created by LHARC on Unix.
- Maybe it is even possible to create LZH files on CP/M! (But this
is a different story...)
