Yes, I find it very sensible. Of course, this could be part of the
gem2deb procedure, overridable in case <lib> is either not correctly
guessed, or in case there is more than one library. The ideal would be
to include every source file shipped as a library - Although there
are many cases where libraries depend on symbols declared on other
libraries, so we cannot just do a recursive "ruby -l $foo" on all
lib/*.rb... But it would be the best way.
