+Description: GNU Scientific Library (GSL) -- Profiling Libraries
+ The GNU Scientific Library (GSL) is a collection of routines for
+ numerical analysis.  The routines are written from scratch by the GSL
+ team in C, and present a modern API for C programmers, while allowing
+ wrappers to be written for very high level languages.
+ .
+ This package contains static libraries compiled with profiling info (-pg)
+ suitable for use with gprof.

+			    Profiling GSL
+
+Sometimes when writing complex code, you may want to profile it using
+gprof. In this case, having libraries with profiling information
+compiled in is invaluable. It is possible to build your own .deb
+containing profiling libraries, that may be installed on your system
+in parallel to the usual libraries. To do this, follow these simple
+instructions: 
+
+i) download the gsl source (and the build dependancies if necessary):
+apt-get source libgsl0
+apt-get build-dep libgsl0
+ii) build a binary profiling package:
+DEB_BUILD_OPTIONS=buildprof dpkg-buildpackage -b -rfakeroot -us -uc
+iii) install the resulting .deb
+dpkg -i ../libgsl0-prof_[version]_[arch].deb
+
+Finally, you need to specify -lgsl_p and -lgslcblas_p to link your
+program against the profiling libraries.
