                     10: We assume that you have installed the PARI library and include files as
                     11: explained in Appendix A or in the installation guide. If you chose
                     12: differently any of the directory names, change them accordingly in the
                     13: Makefiles.

                     15: If the program example that we have given is in the file \kbd{matexp.c} (say
                     16: as the first of several matrix transcendental functions), then a sample
                     17: Makefile might look as follows. Note that the actual file
                     18: {\tt examples/Makefile} is much more elaborate and you should have a look at
                     19: it if you intend to use {\tt install()} on custom made functions, see
