- * From: gatech!skeeve!arnold@eddie.mit.edu (Arnold D. Robbins)
- *
- * Here is deref.c.  It turns texinfo cross references back into the
- * one argument form. It has the same limitations as fixref; one xref per
- * line and can't cross lines.  You can use it to find references that do
- * cross a line boundary this way:
- *
- * 	deref < manual > /dev/null 2>errs
- *
- * (This assumes bash or /bin/sh.)  The file errs will have list of lines
- * where deref could not find matching braces.
- *
- * A gawk manual processed by deref goes through makeinfo without complaint.
- * Compile with gcc and you should be set.
- *
- * Enjoy,
