51: * This file contains the eepic terminal driver, intended for use with the
52: * eepic.sty macro package for LaTeX. This is an alternative to the
53: * latex driver. You need eepic.sty, epic.sty, and a printer driver that
54: * supports the tpic \specials.
55: *
56: * Although dotted and dashed lines are possible with EEPIC, and are
57: * tempting, they do not work well for high-sample-rate curves, mushing
58: * the dashes all together into a solid line. For now anyway, the EEPIC
59: * driver will have only solid lines. Anyone got a solution?
60: *
61: * LATEX must also be defined.
