+.SH DESCRIPTION
+\fB\%@TOE@\fP reports to the standard output stream the (primary) names
+and descriptions of the terminal types available to the \fIterminfo\fP
+library.
+Each \fIdirectory\fP operand is scanned;
+if none are given,
+\fB\%@TOE@\fP scans the the default \fIterminfo\fP directory.
+.SH OPTIONS
+The \fB\-h\fP option can be helpful to observe where \fB\%@TOE@\fP is
+looking for terminal descriptions.
+Other options support maintainers of \fIterminfo\fP terminal
+descriptions.

-If the \fB\-s\fR is also given, \fB@TOE@\fR
-adds a column to the report,

.TP
-\fB\-s\fR
-sort the output by the entry names.
+.B \-h
+writes a heading naming each each directory as it is accessed.
.TP
-\fB\-u\fR \fIfile\fR
-says to write a report to the standard output,
-listing dependencies in the given terminfo/termcap source file.
-The report condenses the \*(``use\*('' relation:
-each line consists of the primary name of a terminal that
-has use capabilities,
-followed by a colon,
-followed by the
-whitespace-separated primary names of all terminals which occur in those use
-capabilities,
-followed by a newline
+.B \-s
+sorts the output by the entry names.
.TP
-\fB\-U\fR \fIfile\fR
-says to write a report to the standard output,
-listing reverse dependencies in the given terminfo/termcap source file.
-The report reverses the \*(``use\*('' relation:
-each line consists of the primary name of a
-terminal that occurs in use capabilities,
-followed by a colon,
-followed by the
-whitespace-separated primary names of all terminals which depend on it,
-followed by a newline.
+.BI \-u\ file
+lists terminal type dependencies in \fIfile\fP,
+a \fIterminfo\fP entry source or \fItermcap\fP database file.
+The report summarizes the \*(``\fBuse\fP\*('' (\fIterminfo\fP) and
+\fBtc\fP (\fItermcap\fP) relations:
+each line comprises the primary name of a terminal type employing
+\fBuse\fP/\fBtc\fP capabilities,
+a colon,
+a space- and tab-separated list of primary names of terminal types thus
+named,
+and a newline.
.TP
-\fB\-v\fR\fIn\fR
-specifies that (verbose) output be written to standard error,
-showing \fB@TOE@\fR's progress.
