The list of files installed is recorded in the compressed text file
%osgeo4w_root%/etc/setup/package-name.lst.gz. When package is
uninstalled only these files are removed. I believe an upgrade action
uninstalls and then installs (rather than simply overwriting in place).
Looking at the file structure of beegis as it installs currently I think
you'd need to provide two packages, "beegis-dev, depends on udig-dev",
and "beegis, depends on udig".
One could perhaps add some logic to a etc/post-install/beegis.bat that
checked for "apps/udig" or "apps/udig-dev" and created junction links to
"apps/beegis"... (would work only on NTFS file systems). Or something of
I don't think there is an equivalent "etc/pre-install/package.bat"
mechanism available which could check and set config settings before
