A short example implementation make runs the following commands: 1) generates tlp from tlsrc/*.tlsrc currently implemented is the auto generation of packages if no pattern is given (see tlsrc/foo.tlsrc) and more complicated patterns (using perl regexp atm). 2) generates a tldb from tlp/*.tlp trivial concatenation with empty lines between 3) moves tlp to tlp.old 4) re-generates the tlp from the tldb use_tldb defines a function read_tldb_file which reads the whole file into a hash 5) compares tlp.old and tlp
