+PARI/GP is a widely used computer algebra system designed for fast computations
+in number theory (factorizations, algebraic number theory, elliptic curves,
+modular forms, L functions...), but also contains a large number of other
+useful functions to compute with mathematical entities such as matrices,
+polynomials, power series, algebraic numbers etc., and a lot of transcendental
+functions. PARI is also available as a C library to allow for faster
+computations.
+
+The build produces a singlethreaded gp binary. If a multithreaded version is
+wanted "--mt=pthread" has to be added as an Configure argument. This however
+created instability in the ploth-function and has therefore been ignored.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
