Subject	Re: [pde-build-dev] Problems with package script and gzipped tars

I have found my files. There is nothing wrong with
tar/tar.gz itself, 
rather, I believe a bug to exist in the script-generating 
"UnzipperGenerator".

Evidence:
If a file is handled as a zip file, it is unzipped twice, once with

<exec executable="unzip" dir="${tempDirectory}/.">
and again, with slightly different parameters, using
<exec executable="unzip" dir="${tempDirectory}/aix.motif.ppc/.">

For tars, there is are corresponding lines

<exec executable="tar" dir="${tempDirectory}/.">
and
<exec executable="tar" dir="${tempDirectory}/.">
where the second call has once again slightly different parameters.

Thus, the root files for the application do not end up in the config 
specific folder as they should, but instead are extracted to the 
platform-independent 'eclipse' folder only.

The relevant methods in the source code are 
UnzipperGenerator.generateUntarRootFiles(String[]) and 
UnzipperGenerator.generateUnzipRootFiles(String[])

I have filed this as bug 174422
