Sample script in docs/mkcloud.md fails

[GarySmith]

The documentation for mkcloud, docs/mkcloud.md, contains a sample bash script in the section "Using with local repositories". The biggest problem with this script is that it suggests that it can be used to create a full cloud and on casual reading seems to execute the additional setup steps mentioned at the top, such as creating the disk and loopback. But the problem is that it skips step (like setuphost) that have to be run in order to work properly. It also has a hardcoded path (/home/tom...) that make it unusable without tweaking. It also changes several network values for no apparent reason.
It appears that the whole point of the script was to demonstrate caching, so instead of having a script, it would be better to document how the caching options work, i.e. cache_clouddata and cache_dir.
