- new behaviour is to do nothing if no platform was specified.
This helps avoid inadvertently removing files.
- support special platforms for compatibility with wmake/wclean targets.
Eg, "wcleanPlatform all"
- allow use from ThirdParty top-level as well, since the directory
structure is similar.
BUG: fix regression in wcleanLnIncludeAll introduced by 9e2e111518
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.
wcleanPlatform is a more general and cleaner version of wcleanMachine
supporting the "-all" option to provide the equivalent of wcleanAll.
Both wcleanMachine and wcleanAll are now deprecated and will be removed
for the next major release.
