As soon as setup.exe hasn't got an option to uninstall a package along with its requirements which have become unused after uninstalling that package, and cygcheck utility also does not provide any information on package dependencies I have written a bash script to list installed Cygwin packages which are not required by any other installed packages (that is package leaves in the dependency tree).
Developers usually have many lib*-devel packages installed on their system, these packages and others are required only as build dependencies so I think this script will be useful primarily for ordinary users who experiment with software and want to keep their Cygwin installation clean. They will be able to check the list of installed packages for unneeded ones. I would like to propose this script as a Cygwin package if you appreciate it. The name of the script can be changed according to Cygwin policy on the use of cyg- prefix for such a type of programs. setup.hint: category: Utils requires: bash coreutils sed wget bzip2 sdesc: "List installed Cygwin packages which are not required by any other installed packages" URLs: http://file.qip.ru/file/ALGWdq2B/setup.html http://file.qip.ru/file/O1wKRdPC/cygcheck-leaves-1.0-1.tar.html --
