pmcyg
A tool for creating offline Cygwin installers.
pmcyg can create customized collections of Cygwin(TM) packages. pmcyg takes a user-supplied list of Cygwin package names, and downloads only them and their dependencies from a Cygwin mirror, e.g. to create a portable off-line installer on CDROM, DVD or USB flash.
