#25 Select package feed commit?

Hi, I'm one of the enthusiastic build-everything-from source types. I'm using librecmc-v1.4.1a-final. On librecmc documentation says to run

./scripts/feeds update && ./scripts/feeds install

I was just wondering (1) How to view/clone the feed repository; and (2) if there is something I can pass to ./scripts/feeds to get a specific repository commit, rather than just whatever happens to be the latest when I run the command?

The package feeds are specified in $SRC_ROOT/feeds.conf.default. If you wish to pull a specific commit instead of a branch, replace ;v1.4 with ^$commit_hash. Currently, libreCMC only has one package feed.

Thank you!
