-// September 23, 2007
-//
-// The instructions below assume you've copied this file and the
-// sample files std_F.cc and std_F.h into a directory where you
-// have write permission.
-//
-// To build std_F.cc, you'll need to run commands similar to
-//
-// g++ -I. -c std_F.cc
-// ar -ru libaff.a std_F.o
-// ranlib libaff.a
-//
-// Respectively, these compile std_F.cc into an object file, std_F.o;
-// create a static library named libaff.a containing the object code;
-// and create an index in libaff.a for the linker, so the library can
-// be used in external programs, such as the one built from this
-// source file. (On Mac OSX, you may need to run ranlib *after* moving
-// the library file to its permanent home.)
-//
-// You may give the library a different name, but it MUST begin "lib"
-// and have the extension ".a": "libblug.a" and "libaff-1.0.a" are all
-// right, but "mylib.a" or "libaff.test" are not. You refer to the
-// library by its name with "lib" and ".a" removed, as in "blug" or
-// "aff-1.0".
-//
-// To compile this source file (the one you're reading now), build
-// libaff.a as described above, then run the command
-//
-// epix -I. -L. -laff std_F.xp
-//
-// Files (such as this one) that use an external library cannot be
-// compiled from emacs, since there is no way to pass the required
-// options; they must be compiled at a shell prompt.
-//
-// Please consult the gcc documentation ("g++ --help") for information on
-// what each option does.
-
-
-// About this file:
-//
-// "F" is the first letter of the Roman alphabet that has no non-trivial
-// symmetries.
-//
-// std_F is a class for representing plane affine maps; please consult
-// the manual for general information of ePiX's plane affine map class.
