Non versioned ports

I suppose that’s what I did, but since you seem to master Mercurial much better than me (frankly, I am a rookie), I’d rather call on your expertise:

I looked at the website of the repository, « commits » page. There are three columns: author, commit # and a comment. I surmised that the commit # would be the right information to be put after the -u option of the ‘clone’ command, so I wrote this for the fetch phase (assuming 52fb22e is the commit #):

fetch {
   system -W ${workpath} \
   "${prefix}/bin/hg clone -u 52fb22e https://bitbucket.org/petebunting/rsgislib rsgislib »
}

Is that correct?

Thanks so much!
