+.SH NAME
+html2four - extract headers from HTML files into four-field lines
+.SH SYNOPSIS
+.B html2four
+[-digit] file*
+command [ argument ...]
+.SH DESCRIPTION
+.I html2four
+extracts information from HTML files and writes it out with four
+tab-separated fields: filename, last label (<a name=> tag) seen,
+header tag type (H[0-9]), and header text. This is an intermediate
+format convenient for generating a permuted index with four2perm(1)
+or a table of contents with a simple awkscript.
+
+The only option is a digit to limit the header levels extracted.
+For example, with -3 only h1, h2, h3 tags are taken. By default,
+it takes h[0-9], though HTML only defines levels 1 to 6.
