Script 'mkrep.sh' is not mentioned in the SDP Guide (Unix).
If this is part of the SDP, it needs to be given at least some basic explanation; if not, consider removing the script from the SDP or move the functionality to another script and update the documentation for that script.
Configuring a replicated environment is now done using this script, but with no mention of it in the guide, no-one knows to look at this script.
