Hi Jano,

Thanks, I was able to strip the ruby directory even further, with your
help and the following script:

------------------------------------------
$OLD_PATH = 'c:\\ruby'
$NEW_PATH = 'c:\\ruby_stripped'

require 'fileutils'

FileUtils.rm_rf($NEW_PATH)
FileUtils.mkdir($NEW_PATH)
FileUtils.cp_r($OLD_PATH + '\\bin', $NEW_PATH + '\\bin')
FileUtils.cp_r($OLD_PATH + '\\lib', $NEW_PATH + '\\lib')
FileUtils.rm_rf($NEW_PATH + '\\lib\\ruby\\gems\\1.8\\doc')
FileUtils.rm_rf($NEW_PATH + '\\lib\\ruby\\gems\\1.8\\cache') 
FileUtils.rm_rf($NEW_PATH + '\\lib\\ruby\\gems\\1.8\\source_cache')
FileUtils.rm_rf($NEW_PATH + '\\lib\\msvcrt-ruby18-static.lib')
FileUtils.rm_rf($NEW_PATH + '\\lib\\msvcrt-ruby18.lib')
FileUtils.rm_rf($NEW_PATH +
'\\lib\\ruby\gems\1.8\gems\fxruby-1.6.12-mswin32\doc')
FileUtils.rm_rf($NEW_PATH +
'\\lib\\ruby\gems\1.8\gems\fxruby-1.6.12-mswin32\rdoc-sources')
FileUtils.rm_rf($NEW_PATH +
'\\lib\\ruby\gems\1.8\gems\fxruby-1.6.12-mswin32\examples')
FileUtils.rm_rf($NEW_PATH +
'\\lib\\ruby\gems\1.8\gems\fxruby-1.6.12-mswin32\tests')
FileUtils.rm_rf($NEW_PATH +
'\\lib\\ruby\gems\1.8\gems\rubyscript2exe-0.5.3')
FileUtils.rm_rf($NEW_PATH +
'\\lib\\ruby\gems\1.8\gems\hpricot-0.6-mswin32')
------------------------------------------

Deleting "cache" and "source_cache" did not harm the system, apparently.

Now, compressed with 7-ZIP, the whole directry is 5.2MB big, which is
more than acceptable for deployement.

I still have to try "Exerb" when I have more time.

Regards,

Philippe
