$ hg help qinit
hg qinit [-c]
init a new queue repository
The queue repository is unversioned by default. If -c is
specified, qinit will create a separate nested repository
for patches (qinit -c may also be run later to convert
an unversioned patch repository into a versioned one).
You can use qcommit to commit changes to this queue repository.
options:
-c --create-repo create queue repository
use "hg -v help qinit" to show global options
