Although we can't create a tar file containing symlinks (a possible
work around could have been to start with a tar file containing
symlinks and add new files to it. Unfortunately we also wanted to
rename "OHRRPGCE-Game.app" to "gamename.app", which wasn't possible)
we at least hoped to be able to extract files containing symlinks
(duplicating the files) but that was broken too!

How does cygwin store file attributes anyway, I wonder? I believe it
stores symlinks as files (similar to the way Unix actually does, or to
Windows .lnk files)

We actually were seriously considering it before having looked at the
file format!
