How to add Mercurial churn extension in TeamCity -

i'd generate hg churn report in teamcity build, churn extension not enabled default in hg. on local box, add churn [extensions] section of mercurial.ini.

where put system wide mercurial.ini teamcity build agent can find , see extension addition? or, better yet, there way add extensions in build step or in teamcity setup?

if able provide teamcity command line arguments mercurial, should able use --config option , enable extension direct path:

hg --config extensions.churn=/path/to/churn.py churn -r 200:300 -a test.py 

that said, believe churn included, though not enabled, in default install first try:

hg --config extensions.hgext.churn= churn -r 200:300  

that worked me locally.

this based on reading churn wiki , using hg help find --config option.
