You can clone with
HTTPS or Subversion.
weird bug, but somebody else may start playing around with this by naming his first sub with something starting with 'sub'.
Tried this a couple of times:
Preparing your 'subfoo' sub!
rm: bin/sub: No such file or directory
ok let's close this. I realized is a by-design constraint. You just can't run the prepare script with a sub name starting with 'sub' because the repo uses 'sub' named files as a template.
Maybe it's worth to change the script and guard and exit with a message.
