- initial split of wmake-related commands into "plumbing" and
"porcelain" akin to how git handles things.
- wmakeBuildInfo (very low-level), now relocated to the wmake/scripts
and accessible for the user as "wmake -build-info".
This satisfies a long-standing desire to access build information
in a fashion similar to the api/patch information.
CONFIG: avoid git information when building with a debian/ directory
- when a 'debian/' directory exists, there is a high probability that
the '.git/' directory is from debian and not from OpenFOAM (ie,
useless here). This corresponds to an implicit '-no-git', which has
no effect when building from pristine sources.
ENH: wmakeCheckPwd becomes scripts/wmake-check-dir
- accessible for the user as "wmake -check-dir" and with 1 or 2
directory names. A wmakeCheckPwd symlink left for compatibility.
