Once installed, this directory contains a Makefile and a small program that you could use as a template when writing your own analysis software. A Makefile.arch is created for each architecture you install with the correct paths and libraries. You will have to link (or copy) the correct makefile to "Makefile" or use the -f option to gmake in order to select a makefile. ---------------------------------------------------------- If you are reading this in the distribution directory, there will be a Makefile.am which automake uses to create a Makefile.in which in turn is converted to a Makefile by the configure script. Note that this is NOT the template makefile - it is called Template.mak, and used to create Makefile.arch at build time. You should NOT touch or copy Makefile.in unless you really know what you are doing - it is a template file used by the configure script to create the real Makefile. If you want to use automake and autoconf yourself, look in the contrib directory of the distribution.
