-# makefile for Triangle and Show Me
-#
-# Type "make" to compile Triangle and Show Me.
-#
-# After compiling, type "triangle -h" and "showme -h" to read instructions
-#   for using each of these programs.
-#
-# Type "make trilibrary" to compile Triangle as an object file (triangle.o).
-#
-# Type "make distclean" to delete all object and executable files.
-
-# SRC is the directory in which the C source files are, and BIN is the
-#   directory where you want to put the executable programs.  By default,
-#   both are the current directory.
-
-SRC = ./
-BIN = ./
-
-# CC should be set to the name of your favorite C compiler.
-
-CC = cc
-
-# CSWITCHES is a list of all switches passed to the C compiler.  I strongly
-#   recommend using the best level of optimization.  I also strongly
-#   recommend timing each level of optimization to see which is the
-#   best.  For instance, when I had a DEC Alpha using DEC's optimizing
-#   compiler, the -O2 switch generated a notably faster version of Triangle
-#   than the -O3 switch.  Go figure.
-#
-# By default, Triangle and Show Me use double precision floating point
-#   numbers.  If you prefer single precision, use the -DSINGLE switch.
-#   Double precision uses more memory, but improves the resolution of
-#   the meshes you can generate with Triangle.  It also reduces the
-#   likelihood of a floating exception due to overflow.  Also, it is
-#   much faster than single precision on many architectures.  I recommend
-#   double precision unless you want to generate a mesh for which you do
-#   not have enough memory to use double precision.
-#
-# If yours is not a Unix system, use the -DNO_TIMER switch to eliminate the
-#   Unix-specific timer code.  Also, don't try to compile Show Me; it only
-#   works with X Windows.
-#
-# To get the exact arithmetic to work right on an Intel processor, use the
-#   -DCPU86 switch with Microsoft C, or the -DLINUX switch with gcc running
-#   on Linux.  The floating-point arithmetic might not be robust otherwise.
-#   Please see http://www.cs.cmu.edu/~quake/robust.pc.html for details.
-#
-# If you are modifying Triangle, I recommend using the -DSELF_CHECK switch
-#   while you are debugging.  Defining the SELF_CHECK symbol causes
-#   Triangle to include self-checking code.  Triangle will execute more
-#   slowly, however, so be sure to remove this switch before compiling a
-#   production version.
-#
-# If the size of the Triangle binary is important to you, you may wish to
-#   generate a reduced version of Triangle.  The -DREDUCED switch gets rid
-#   of all features that are primarily of research interest.  Specifically,
-#   defining the REDUCED symbol eliminates the -i, -F, -s, and -C switches.
-#   The -DCDT_ONLY switch gets rid of all meshing algorithms above and beyond
-#   constrained Delaunay triangulation.  Specifically, defining the CDT_ONLY
-#   symbol eliminates the -r, -q, -a, -u, -D, -S, and -s switches.  The
-#   REDUCED and CDT_ONLY symbols may be particularly attractive when Triangle
-#   is called by another program that does not need all of Triangle's
-#   features; in this case, these switches should appear as part of
-#   "TRILIBDEFS" below.
-#
-# On some systems, you may need to include -I/usr/local/include and/or
-#   -L/usr/local/lib in the compiler options to ensure that the X include
-#   files and libraries that Show Me needs are found.  If you get errors
-#   like "Can't find include file X11/Xlib.h", you need the former switch.
-#   Try compiling without them first; add them if that fails.
-#
-# An example CSWITCHES line is:
-#
-#   CSWITCHES = -O -DNO_TIMER -DLINUX -I/usr/X11R6/include -L/usr/X11R6/lib
-
-CSWITCHES = -O -DLINUX -I/usr/X11R6/include -L/usr/X11R6/lib
-
-# TRILIBDEFS is a list of definitions used to compile an object code version
-#   of Triangle (triangle.o) to be called by another program.  The file
-#   "triangle.h" contains detailed information on how to call triangle.o.
-#
-# The -DTRILIBRARY should always be used when compiling Triangle into an
-#   object file.
-#
-# An example TRILIBDEFS line is:
-#
-#   TRILIBDEFS = -DTRILIBRARY -DREDUCED -DCDT_ONLY
-
-TRILIBDEFS = -DTRILIBRARY
-
-# RM should be set to the name of your favorite rm (file deletion program).
-
-RM = /bin/rm
