# Shewchuk's triangulation routine used in some parts of GMT is not 
# distributed under the GNU Public Licence. If you work for a for-profit
# organisation, you should read Shewchuk's copyright statement (in 
# $PKG/src/README.TRIANGLE) first. 
# This script enables the (much faster) Shewchuk triangulation routine 
# by default; should you need to change this behaviour, set SHEWCHUK to 
# "no" below:
SHEWCHUK=${SHEWCHUK:-yes}

# There are a number of different resolution coastline files available
# for GMT, and their size on disk varies from <2MB (low) to 61.7MB 
# (full). They come in 3 separate archives (GSHHS1.10_coast, 
# GSHHS1.10_high and GSHHS1.10_full). The first contains the low, intermediate
# and coarse resolutions, the second the high resolution, and the third
# the full resolution. I prefer to have them all installed (disk space
# is cheap), but you may not. By default, all three sets will be installed, 
# unless you choose otherwise below.
# e.g. ${COASTS:-"coast"} would install only the low, intermediate and
# coarse resolutions. At least one resolution is required.
