[Steve Cassidy]: "Trf lets you zip up a bit of data but doesn't provide the machinery to zip
directories or files. mkZipLib
provides such an interface as does zvfs
. More up to date is the zipvfs
package which is part of tclvfs but that doesn't seem to be working cleanly
yet and requires tcl8.4 features."
