My DIY solution Re: Cygwin setup.exe: Clean historical setup packages

Tue Dec 1 12:31:00 GMT 2009

After I viewed setup.ini, I decide to write a little script to do this.
Currently, it scans all the sub-directory of cygwin local package directory,
and delete all the old files which not listed in setup.ini or setup-2.ini.
Wish it can help someone like me. 
download it from nabble.com:
http://old.nabble.com/file/p26590979/cleanOldPackages_UTF8.sh
cleanOldPackages_UTF8.sh 
or copy the following code to a .sh file:
<pre>
#
# 将本脚本文件放到与 setup.exe 相同的目录下，然后执行之
# Put this script file to the directory which contains setup.exe, and
execute it
