Feature request: "bzr check-install"

[Matthieu Moy]

Hi,

I've just installed bzr on an "old" Fedora Core 2, which had none of
bzr's dependancies or recommandation as .rpm package.

It was quite a pain indeed: after "bzr" started to work, I still had
to install paramiko, which itself didn't work until I installed
pycrypto (giving no relevant error message, so a beginner would have
been completely lost here, but this is a known bug).

Then, I installed cElementTree because I knew it was nice to have it.

Something that would have considerably eased my life then would be a
command to check that the installation is complete. A kind of short
and user-friendly "bzr selftest":

$ bzr check-install
bzr works: yes
sftp works: no (missing pycrypto)
cElementTree installed: no (bzr will still run, but slower)
$ 

or

$ bzr check-install
bzr works: yes
sftp works: yes
cElementTree installed: yes
All dependancies and recommandations are satisfied
$ 

It should be relatively easy to implement, and would considerably
improve the first contact of beginners requiring to install bzr
themselves.
