#     wmakeLnInclude
#
# Description
#     Link all the source files in the <dir> directory into <dir>/lnInclude
#
#     Usage: wmakeLnInclude [-f] <dir> [-lnOption]
#
#     The desired source files:
#         *.C *.H *.h *.cpp *.cxx *.hpp *.hxx
#
#     Avoid
#         *.c (C source)

usage: $Script [-f] <dir> [-lnOption]

    Link all the source files in the <dir> into <dir>/lnInclude

Note
    The '-f' option forces an update when the lnInclude directory already exists
    and also changes the default linking from 'ln -s' to 'ln -sf'.

USAGE
