16.5 Sage and other computer algebra systems

If foo is a Pari, GAP (without ending semicolon), Singular, Maxima command, resp., enter gp("foo") for Pari, gap.eval("foo"), singular.eval("foo"), maxima("foo"), resp.. These programs merely send the command string to the external program, execute it, and read the result back into Sage. Therefore, these will not work if the external program is not installed and in your PATH.
