The Tesseract Package Manager is similar to
Linux-based operating systems' package managers.

The repository data is stored in the
'/system/data/package.dat' file.

Programs that compose the TPM are:

tpm-install <package>:  Install a package
tpm-list <listing>:     List available packages
tpm-recache:            Redownload package.dat
tpm-remove <package>:   Remove a package

The tpm-list utility accepts a listing type as a
parameter. You can list available packages
('available') or installed ones ('installed').
