how do i close a branch on mercurial without using "hg ci --close-branch"?

for some reason "hg ci --close-branch" is coming up as an command not found in my mercurial. how do I get around this to close the branch in a different way?开发者_如何学编程

thanks!

Your mercurial is too old. Close branch was added in version 1.6 or 1.7. You should upgrade, which is quite easy on most any platform.

Failing that there's no way to close a branch, but you can make it inactive by merging it into another branch. Both closed and inactive non-final for a named branch -- they never really go away.
