AptitudeUpdateScript

@@ +1 @@
+These scripts were written to enable the quick and easy updating of packages and the Changelog.
+
+The following two scripts, {{{a-up}}} and {{{logchanges}}}, they are installed on PenguinServer and can be used to do system updates and record the updates in /root/Changelog. The contents of the Changelog is then emailed to root by [https://labs.riseup.net/code/projects/metche metche] so that the people working on the server know what updates have been applied.
