Clarify README.HACKING
As an alternative, if you have your patch in a git repository, you can edit projects/firefox/config to change the git_url option to point to your git repository, and change the git_hash option to point to the commit you want to build. You will also need to comment the 'tag_gpg_id: 1' line (unless git_hash is pointing to a signed git tag).
I presume the current value of git_hash is a tag (and not a branch) right? It'd be good to explain that.
Even better would be if we could build off branches. I guess my ideal situaiton would be:
As an alternative, if you have your patch in a git repository, you can edit projects/firefox/config to change the git_url option to point to your git repository.
You can specify git_hash to build off a commit hash or tag, OR git_branch to build off a branch. (If both are specified, it is an error.) git_branch may be 'remotename/branchname' in which case the remote branch is
git fetch
-ed and then built; or 'branchname' in which case the local branch isgit checkout
-ed and then built.
