typical g++ compile options

-Wall : display a maximum number of warnings
-fPIC : necessary for correct DSO treatment. Much more info here: http://people.redhat.com/drepper/dsohowto.pdf

EPS to PDF size conservation

To print EPS images into PDF files with paper size equal to EPS bounding box, use the epstopdf script or LATEX package described here: http://www.ctan.org/pkg/epstopdf

gsl library usage

source file : inlcude "/gsl/foo.h"
makefile : gcc ... -lgsl -lgslcblas
the former is necessary to load supporting CBLAS library for linear algebra

Under typical linux folder hierarchy, usr/local/include is the place to dump "orphan" .h and .hh files. This folder is normally visited by g++ when looking for includes.
