/*
* TODO in future work:
*
+ * - the index should not refer to the contents, if an indexable
+ * term crops up in a section title!
+ *
+ * - include the version IDs.
+ *
* - linearised PDF, perhaps?
*
* - compression of output files. For the actual text display,
* * we need to parse the font to extract its metrics
* * then we pass the font bodily to both PS and PDF so it can
* be included in the output file
+ *
+ * - character substitution for better typography?
+ * * fi, fl, ffi, ffl ligatures
+ * * use real ellipsis rather than ...
+ * * a hyphen in a word by itself might prefer to be an en-dash
+ * * (Americans might even want a convenient way to use an
+ * em-dash)
+ * * substituting `minus' for `hyphen' in the standard encoding
+ * is probably preferable in Courier, though certainly not in
+ * the main text font
+ * * if I do do this lot, I'm rather inclined to at least try
+ * to think up a configurable way to do it so that Americans
+ * can do em-dash tricks without my intervention and other
+ * people can do other odd things too.
