which may be optionally overridden by version-specific rules.
For example the default rules for gcc on GNU/Linux x86_64 are in the
wmake/rules/linux64Gcc directory. If there is a need to change any of
the rules for a specific version of gcc, e.g. gcc-4.8.4 the directory
wmake/rules/linux64Gcc48 may be created into which any of the language
files may be provided containing the rules to override the defaults.
The Makefiles are now in the makefiles sub-directory
The "-f | -force" option in wmakeLnInclude is now "-u | -update" for
consistency with the other scripts.
The "Usage" entry in the headers is now consistently formatted in all
scripts.
