- was for parallel compilation across multiple hosts, but less useful
with modern CPUs with higher number of cores and/or hyperthreading.
Fragile use and dependent on a 'lockfile' utility that is not often
installed.
- unknown options or missing option values now emit a shorter message
without the entire usage. This makes it easier to identify the errors
and is better aligned with the behaviour of GNU system tools.

$ simpleFoam -case
Using: OpenFOAM-plus (see www.OpenFOAM.com)
Build: plus-01234
Error: option '-case' requires an argument
See 'simpleFoam -help' for usage
====
- provide for reduced (-help) and full (-help-full) usage information.
In many cases the reduced usage provided sufficient and easier
to find the information.
- make -srcDoc an alias for -doc-source
- no warnings about option aliases for future dates.
wmakeCollect collects the compilation commands for the all of the object
files to be compiled into a single makefile which is passed to make to
schedule the compilations in parallel efficiently.
Before wmakeCollect can be called the lnInclude directories must be
up-to-date and after wmakeCollect the linkage stage of the compilation
must executed using wmake.
This entire process is now handled by wmake using the new '-queue' or
'-q' option to compile sections of the OpenFOAM source tree or the
entire tree efficiently. The number of cores the compilation executes
on may be specified either using the WM_NCOMPPROCS variable or the '-j'
option.
To efficiently compile OpenFOAM after a 'git pull' the '-update' option
is provided which updates lnInclude directories, dep files and removes
deprecated files and directories. This option may be used with '-q':
wmake -q -update
