前些日子在用apt-cyg/cyg-apt來更新自己的cygwin安裝包，太TMD讓人心焦了。于是自己寫了一個"yum for cygwin"，功能還行吧，我需要的都有了。分享一下。

YUM for cygwin is a shell script helping cygwin user to install/update/search
packages of cygwin in the manners of similar to redhat yum functions.
Usage: $PROGNAME [COMMAND] [OPTION] [PARAMETERS]
Commands:
check-updates List all possible updates of installed package(s)
for cygwin as of now.
clean Clean all cache files and refresh them with latest
data.
info [pkgs..] Display the briefing information of the given package(s)
info installed Display the briefing information of installed package(s)
info updates Display the briefing information of updating package(s)
install [pkgs..] Install the given package(s) with required package(s)
list [pkgs..] List the detail information of the given package(s)
list installed List the detail information of the installed package(s)
list updates List the detail information of the updating package(s)
remove [pkgs..] Remove the installed package(s) given by user as well
as the orphan package(s) relatives.
search key-word Search the package database for any package(s) relevant
the given keyword.
update [pkgs..] Update all packages or the package(s) given by user.
full-cache Retrive all information from cygwin in cache, it takes
long time to complete while internet connection is slow.
Options:
-y, --yes Always say yes to queries
-h, --help Show current help message of the script usages
Please Report Script Bugs to $AUTHOR_MAIL
