|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is an extremely simple documentation generator that generates
|
|
a BSD man page from a specially-formatted C header file.
|
|
See
|
|
.Xr hdoc 5
|
|
for details on the format of this header file.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl i Ar file
|
|
The input C header file to read from. If this option is omitted,
|
|
then the standard input is read.
|
|
.It Fl o Ar file
|
|
The output BSD man page file to write. If this option is omitted,
|
|
then the standard output is written.
|
|
.It Fl D Ar key=value
|
|
Set the register
|
|
.Ar key
|
|
to
|
|
.Ar value .
|
|
.Nm
|
|
registers are used in various places, and can be set in either
|
|
the header file, or on the command line. Setting registers that
|
|
should be the same in all headers is best done from the command
|
|
line for maintainability purposes, but header-specific values
|
|
should be set in the header file itself.
|
|
.Pp
|
|
Registers are explained in more detail in
|
|
.Xr hdoc 5 .
|
|
.El
|
|
.Sh RETURN VALUE
|
|
.Pp
|
|
.Nm
|
|
returns a success value if the header is well-formed and the
|
|
man page is successfully generated. It returns an error code in
|
|
all other scenarios.
