> Afterwards I could do:
> 
> /share/software/OpenJDK> hg clone http://hg.openjdk.java.net/jdk7/jdk7/
> jdk7
> requesting all changes
> adding changesets
> adding manifests
> adding file changes
> added 2 changesets with 26 changes to 26 files
> 26 files updated, 0 files merged, 0 files removed, 0 files unresolved

> So everything worked fine! Note that I'm behind a firewall, but
> Mercurial correctly picked up my http proxy from the  "http_proxy"
