+.
+.SH "DESCRIPTION"
+.
+The
+.B archtab
+file is a sequence of lines. A line may be blank, a comment, or a table
+entry. Blank lines contain only whitespace; comments have a
+.RB ` # '
+as their first non-whitespace character: both are ignored. Table
+entries consist an architecture name and a hostname, separated by
+whitespace. Each architecture should only appear once. The hostname
+should be the preferred host for building software on that architecture.
