Why do I get hg: unknown command 'convert' althought running hg 1.7.3?

I'm 开发者_运维技巧trying to convert an svn repo to mercurial but I fail.

hg: unknown command 'convert'
Mercurial Distributed SCM


$ hg --version
Mercurial Distributed SCM (version 1.7.3)

To check which extension commands currently are available, run hg help extensions. It lists enabled as well as disabled extensions.
