=head1 SYNOPSIS
use Pod::Text::Overstrike;
Pod::Text::Overstrike is a simple subclass of Pod::Text that highlights
output text using overstrike sequences, in a manner similar to nroff.
-Characters in bold text are overstruck (character, backspace, character) and
-characters in underlined text are converted to overstruck underscores
-(underscore, backspace, character). This format was originally designed for
-hardcopy terminals and/or lineprinters, yet is readable on softcopy (CRT)
-terminals.
+Characters in bold text are overstruck (character, backspace, character)
+and characters in underlined text are converted to overstruck underscores
+(underscore, backspace, character). This format was originally designed
+for hard-copy terminals and/or line printers, yet is readable on soft-copy
+(CRT) terminals.
Overstruck text is best viewed by page-at-a-time programs that take
advantage of the terminal's B<stand-out> and I<underline> capabilities, such
