Here are three documents that make up the SPICE manual provided by the University of California at Berkeley, the birthplace of SPICE.
Note: If the font is hard to read in ghostview, chose Magstep = 1.
BJT specific information starts at page 33 and MOSFET info at 37 of the Manual.
There are many other implementations of SPICE which are generally interchangeable with respect to I/O format. ICCAP can use almost any of them for it's simulation and optimization functions.
