# Description
# Reduced argument parser (eg, for scripts using wmake)
# that handles some common parameters
#
# Usage
# # Parse the arguments by sourcing this script
# . ${WM_PROJECT_DIR:?}/wmake/scripts/wmake.wmake-args
#
# Options
# -s | -silent | -quiet
# Exports WM_QUIET=true
#
# -j | -jN | -j N
# Compile using all or specified N cores/hyperthreads
#
#------------------------------------------------------------------------------
# NB: nArgs to track the current processing position to avoid wraparound
# when checking for optional parameters (eg, the -j processing)
