Correct way of providing CDAT version information ?

[jypeter]

Could you document on the web site (and the wiki) the best way that a CDAT user can determine the version of CDAT s/he is using and let you know about it? This may seem straightforward, but I'm dealing with several installed versions of CDAT on several servers and this is going to get worse if I add Python 3 versions

I know that you can use conda list

>conda list | \grep '^cdat'
cdat                      8.0                           0    cdat/label/v80
cdat_info                 8.0                      py27_0    conda-forge

>conda list | \grep '^cdat'
cdat                      8.0                           0    cdat/label/v80
cdat_info                 8.0                   py36_1002    conda-forge

I have also seen @doutriaux1 mention cdat_info several times in the issues, but I don't really know what's the best way to use cdat_info. help(cdat_info) and https://cdat-info.readthedocs.io/en/latest/ don't provide much help

If you document this, you can probably add a link to it from the Found a bug in CDAT? section at the bottom of the Contact page and ask the users to report precisely which version they are using
