+f2c is a Fortran-to-C converter.
+
+This package includes libf2c, which must be linked to the resulting C
+code. Thus the general idea is
+
+ f2c foo.f
+ gcc foo.c -lf2c
+
+Or use the fc script provided in the docs directory. Beware, fc is also
+a bash builtin.
+
+If combining with gfortran, you may want to use the gfortran -ff2c
+option. See the gfortran man page.
