Lazarus - sources for the console archiver

Using the ZLib library, I wrote such a simple archiver-unzip.
For the command line.

That is, to pack the DOCS folder into the DOCS.ZZ archive, write the command:
zz d docs docs.zz
To pack the FILE.DOC file into the FILE.ZZ archive write
zzf file.doc file.zz
The most convenient way to retrieve is to use the HERE attribute - here:
zz docs.zz here
zz file.zz here
