From 5dc1015e9666ef59682c46e306ed3a4add0a9356 Mon Sep 17 00:00:00 2001 From: Christopher James Lahey Date: Sat, 10 Jun 2000 21:13:07 +0000 Subject: Added e-printable.c and e-printable.h. 2000-06-10 Christopher James Lahey * Makefile.am: Added e-printable.c and e-printable.h. * e-printable.c, e-printable.h: This new class is a printing context.
