SYNOPSIS

  apt-cyg [operation] [options] [targets]

DESCRIPTION

  apt-cyg is a package management utility that tracks installed packages on a
  Cygwin system. Invoking apt-cyg involves specifying an operation with any
  potential options and targets to operate on. A target is usually a package
  name, file name, URL, or a search string. Targets can be provided as command
  line arguments.

OPERATIONS

  depends
    Produce a dependency tree for a package.

  rdepends

    Search each locally-installed package for names that match regexp. If no
    package names are provided in the command line, all installed packages will
