+EPSON Image Scan! for Linux enables you to print to a networked
+all-in-one EPSON printer.  A SANE 'epkowa' backend is provided
+as well; scanning over the network requires the additional

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
