Subject: [PATCH 1/2] Added support for pre and post commands

Two new fields were added to the config. Precmds runs before cmds and
links. Postcmds runs after cmds and links. Cmds is no longer necessary
but was left in for compatibility.

Subject: [PATCH 2/2] Adopt changes required by upstream maintainer This commit
 switches indentation to tabs, rather than spaces, removes an unnecessary
 conditional check and adopts the project naming convention. It also updates
 the documentation to reflect the changes it creates.
