I would like to change the name of a bookmark that I previously set using
hg bookmark xyz
How can I rename a bookmark in mercurial?
U wanna 2 read docs, namely hg help book in order to discover needed options
>hg book
* master 1195:b800644fcbe2
>hg book mainline -m master
>hg book
* mainline 1195:b800644fcbe2
