This file is part of Free Pascal build tools
Copyright (c) 2014-2015 by Tomas Hajny, member of the FPC core team.
This program processes one or more listing files created with fpmake
(e.g. using 'fpmake pkglist --target=<FPC_target> -zp units-' for
unit packages or without the '-zp <prefix>' for utils), compares
them to the text-mode installer configuration file install.dat and
creates file install.add which provides information about packages
missing in install.dat in a form allowing copy&paste of individual
lines into install.dat.
If the original description of a certain package as found in fpmake.pp
is too long for install.dat, the maximum length is marked
in the respective line in install.add using a pipe character ('|').
