+# 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
