+# Background: Humans use a number of dash-like characters:
+#
+#   - ASCII hyphen/minus needed for command-line options and other computer
+#     input;
+#   - hyphen (`one-to-one');
+#   - en dash (`2000-2003');
+#   - em dash -- like this.  [Not currently handled.]
+#
+# Troff input spells them as \-, -, \[en], \[em] respectively.  (See the
+# groff_char.7 man page for a full list of such punctuation characters.)  If
+# you run `man' with your LC_CTYPE indicating a rich character set like unicode
+# (UTF-8 encoding), then it uses different output characters for each of the
+# above.
+#
+# In particular, if your man page source has plain `-' when giving an example
+# of a flag or command or other program input, then users won't be able to use
+# mouse copy&paste from the formatted man page.
+
+# This script is something of a hack: it is only big enough to handle a few man
+# pages of interest (produced by pod2man).  You should manually check the
+# changes it makes.
+
+# Approach: we handle each line a word at a time, and typically make the same
+# hyphen-vs-ASCII decision throughout the word.  We're a bit haphazard about
+# word-splitting, but it's hard to find an example of where we'd be hurt by
+# that, and by luck we would do the right thing for many gcc options like
+# `-fconstant-string-class=\fICLASS-NAME\fR' (where CLASS-NAME should use a
+# hyphen and the others should be ASCII hyphen-minus).
+#
+# Perl's /e (execute) flag for substitutions does just what we want
+# for preserving non-word bits while transforming "words".
+#
+# We don't currently handle special things like `apt-get' that look like
+# hyphenated english words but are actually program names.  In general the
+# problem is AI complete, e.g. `apt-gettable' could be either hyphen (gettable
+# by apt) or ASCII hyphen-minus (able to be processed by the `apt-get'
+# program).
+#
+# We don't currently take hints from font choice.  (E.g. text in CR font should
+# probably use ASCII hyphen-minus.)
+#
+# We currently only handle a couple troff requests and escapes (see groff.7).
