# (1) Code section description:
#     CmdMain  - Developer code section. This is where your work gets done.
#     <Implement your subs here>  - Developer subs code section. This is where you write subs.
#
# (2) Reserved Variables -
#        $ENV{HELP} - Flag that specifies usage.
#        $ENV{lang} - The specified language. Defaults to USA.
#        $ENV{logfile} - The path and filename of the logs file.
#        $ENV{logfile_bak} - The path and filename of the logfile.
#        $ENV{errfile} - The path and filename of the error file.
#        $ENV{tmpfile} - The path and filename of the temp file.
#        $ENV{errors} - The scripts errorlevel.
#        $ENV{script_name} - The script name.
#        $ENV{_NTPostBld} - Abstracts the language from the files path that
#           postbuild operates on.
#
# (3) Reserved Subs -
#        Usage - Use this sub to discribe the scripts usage.
#        ValidateParams - Use this sub to verify the parameters passed to the script.
#
# (4) Call other executables or command scripts by using:
#         system "foo.exe";
#     Note that the executable/script you're calling with system must return a
#     non-zero value on errors to make the error checking mechanism work.
#
#     Example
#         if (system("perl.exe foo.pl -l $lang")){
#           errmsg("perl.exe foo.pl -l $lang failed.");
#           # If you need to terminate function's execution on this error
#           goto End;
#         }
#
# (5) Log non-error information by using:
#         logmsg "<log message>";
#     and log error information by using:
#         errmsg "<error message>";
#
# (6) Have your changes reviewed by a member of the US build team (ntbusa) and
#     by a member of the international build team (ntbintl).
