# igmt_configure.tcl -- global variables and default settings
# change path names and other things here, not anywhere else
# better still: use a igmt_siteconfig.tcl file to reset the variables
# of your choice. this file gets read in (if it exists) so that you can
# override our defaults.
#
# global variables were chosen for simplicity, so if you introduce new ones
# check here
#
#
# most common changes:
#
# - gmt binary location: lower_version_gmtbins and higher_version_gmtbins
#	change these to point to the location of the 
#	GMT binaries
# 
# - rasterpath variable (line ~220), to point to the main directory that holds 
#   the raster data
#
# you can put both these changes into the igmt_siteconfig.tcl file
#
#
# part of the iGMT package
