+     "This package mainly meant for caching packages of Debian or Debian
+based distributions (like Trisquel) through HTTP.  It also has partial support
+for HTTPS and other distributions / repositories (OpenSUSE, Arch Linux,
+Sourceforge mirror network, Cygwin mirrors) as this requires more
+configuration and comes with some limitations.  Packages can be imported
+manually either by copying files from another apt-cacher-ng instance or by
+importing them from CD, DVD, jigdo, etc.  While apt-cacher-ng can work offline,
+it requires some online access before that to build valid index files.  It also
+supports partial mirroring.  It can be configured through configuration files
+and/or a web interface and/or a command line tool.")
