I afraid I missed something important: I have a receipt, put it to /home/slitaz/wok//, I found the command
tazwok genpkg
but I don't know where to put the files to that have to be put into this package. I do not want tazwok to compile something, I already have the binaries. So how do I tell tazwok to use my files?
There are two types of packages: those that are pre-built binaries that are unpacked in to a filesystem (tazpkg used to package and install); others are source code that gets compiled, then unpacked (made with tazwok, installed with tazpkg).
As you have binaries, the command you want is tazpkg pack rather than using TazWok.
You should be able to find the Handbook or manual page somewhere. I can't remember the details as I'm on Fedora atm, but if you unzip a simple package, you should be able to work out the format.
