Gnucap (GNU Circuit Analysis Package) is a free and open-source circuit simulator. The syntax is very similar to SPICE - and circuit descriptions written for Gnucap might in fact work with SPICE with very little modification.
A lot of students (and probably working engineers as well) are familiar with programs such as OrCAD, PSPICE, etc., which use SPICE as a circuit simulator in the background. What these programs actually do is generate a SPICE netlist - similar to the one shown below.
