#  Install PGPLOT from dir=$NEMO/local/pgplot into lib=$NEMOLIB
#
#  NOTE: Although meant for ease of install within $NEMO, you 
#  may also find this file within the WIP distribution.
#  The master version should however stay within NEMO
#  
#
#  3-apr-01	allowed final directory also to be configurable
#		and some NEMO V3 support added
#  9-apr-01     added support if file= is given to directly specify pgplot tar ball
# 11-jun-01     for new pgplot file name convention (520, 521, 522....)
# 11-jan-02     also allow pgplot directory in $NEMO/local/pgplot
#  9-apr-02     fixed caltech links
#  5-dec-02     added tcl/tk driver for carma
# 29-jun-03     added darwin (tested w/ MacOSX 10.2)
# 23-jan-04     fixed linux when CC and F77 present (e.g. intel compiler)
# 27-mar-04     force rebuilding some executables upon reload (+typo fix)
# 28-jun-04     debug option
# 20-may-05     make script more generic, less dependant on NEMO, and distribute with WIP
# 10-jul-05     removed the always problematic never used TKDRIV driver
# 16-jul-05     removed pp,gi,wd from drivers for gfortran
#  5-dec-05     abuse the new 4th (optional) argument to makemake
# 31-aug-06     add optional png
# 26-sep-06     use fix64bit.csh if on 64 bit (or use int8=1)
# 25-oct-07     note that gcc 4.2.2 compiles GI/PP/
