[schilytools] running compression tests

[Robert Clausecker]

Hi Dennis,

Thank you for the report!

The background is as follows: star tries to call compressors without
arguments and decompressors with just -d as an argument.  While this
works for most compressors I tried, it fails for some of the weirder
ones like lzma(1).  It appears that those require a different syntax
to work.

I would like to understand if these decompressors used to work on some
platforms or if the code just never worked in the first place.  Then,
I may be able to rewrite the code such that it works both on current and
more exotic platforms.

You can run the decompressor tests yourself: install star from the
schilytools distribution, then enter the directory star/tests/compress
in current schilytools and run compress.sh.  Please report any failures
you see.  You might need to install additional compression programs.
If possible and you have the time, please do so from the official or
most common source of third party software for your system.

Please report results on various platforms either here or on Codeberg:

Yours,
Robert Clausecker
