# Regions geneartion algorithm:
# (TODO)
#
# Author: Zhenghao ZHU
# Created: ???
#
# Change logs:
# 2017-02-26, Weitian LI
# * Further simplify arguments handling
# * Remove test support (-t) for simplification
# * Rename 'stn' to 'SNR'
# * Add ds9 view
# v2.0, 2015/06/03, Weitian LI
# * Copy needed pfiles to current working directory, and
# set environment variable $PFILES to use these first.
# * Added missing punlearn
# * Removed the section of dmlist.par & dmextract.par deletion
# minimal counts
