.P
The command line is parsed in accordance with normal GNU conventions,
but with one exception \(em when specifying any short form option
(i.e., a single character option introduced by a single hyphen),
and if that option expects an argument, then it
.I must
be specified independently (i.e., it may
.I not
be appended to any group of other single character short form options).
.P
Long form option names (i.e., those introduced by a double hyphen)
may be abbreviated to their minimum length unambigous initial substring.

.
.SH DESCRIPTION
.B pdfroff
is a wrapper program for the GNU text processing system,
.BR groff .
It transparently handles the mechanics of multiple pass
.B groff
processing, when applied to suitably marked up
.B groff
source files,
such that tables of contents and body text are formatted separately,
and are subsequently combined in the correct order, for final publication
as a single PDF document.
A further optional
.Q style\0sheet
capability is provided;
this allows for the definition of content which is required to preceed the
table of contents, in the published document.
.P
For each invocation of
.BR pdfroff ,
the ultimate
.B groff
output stream is post\(hyprocessed by the GhostScript interpreter,
to produce a finished PDF document.
.P
.B pdfroff
makes no assumptions about, and imposes no restrictions on,
the use of any
.B groff
macro packages which the user may choose to employ,
in order to achieve a desired document format;
however, it
.I does
include specific built in support for the
.B pdfmark
macro package, should the user choose to employ it.
Specifically, if the
.I pdfhref
macro, defined in the
.B pdfmark.tmac
package, is used to define public reference marks,
or dynamic links to such reference marks, then
.B pdfroff
will perform as many preformatting
.B groff
passes as required, up to a maximum limit of
.IR four ,
in order to compile a document reference dictionary,
to resolve references, and to expand the dynamically defined
content of links.
.
.\" --------------------------------------------------------------------
.
.SH USAGE
.B pdfroff
usage closely mirrors that of
.B groff
itself.
Indeed,
with the exception of the
.BR \-h ,
.BR \-v ,
and
.BI \-T \0dev
short form options, and
all long form options,
which are parsed internally by
.BR pdfroff ,
all options and file name arguments specified on the command line are
passed on to
.BR groff ,
to control the formatting of the PDF document.
Consequently,
.B pdfroff
accepts all options and arguments, as specified in
.BR groff (@MAN1EXT@),
which may also be considered as the definitive reference for all standard
.BR pdfroff
options and argument usage.
.
.\" --------------------------------------------------------------------
.
.SH OPTIONS
.B pdfroff
accepts all of the short form options
(i.e., those introduced by a single hyphen),
which are available with
.B groff
itself.
In most cases, these are simply passed transparently to
.BR groff ;
the following, however, are handled specially by
.BR pdfroff .
.TP
.B \-h
Same as
.BR \-\-help ;
see below.
.TP
.B \-i
Process standard input, after all other specified input files.
This is passed transparently to
.BR groff ,
but, if grouped with other options, it
.I must
be the first in the group.
Hiding it within a group will
break standard input processing, in the multiple pass
.B groff
processing context of
.BR pdfroff .
.TP
.BI \-T \0dev
Only
.BI \-T \0ps
is supported by
.BR pdfroff .
Attempting to specify any other device will cause
.B pdfroff
to abort.
.TP
.B \-v
Same as
.BR \-\-version ;
see below.
.P
See
.BR groff (@MAN1EXT@)
for a description of all other short form options,
which are transparently passed through
.BR pdfroff
to
.BR groff .
.P
All long form options
(i.e., those introduced by a double hyphen)
are interpreted locally by
.BR pdfroff ;
they are
.B not
passed on to
.BR groff ,
unless otherwise stated below.
.TP
.B \-\-help
Causes
.B pdfroff
to display a summary of the its usage syntax, and supported options,
and then exit.
.TP
.B \-\-no\-pdf\-output
May be used with the
.BI \-\-reference\-dictionary= name
option (described below) to eliminate the overhead of PDF formatting,
when running
.B pdfroff
to create a reference dictionary, for use in a different document.
.TP
.B \-\-no\-reference\-dictionary
May be used to eliminate the overhead of creating a reference dictionary,
when it is known that the target PDF document will contain no public
references, created by the
.I pdfhref
macro.
.TP
.B \-\-no\-toc\-relocation
May be used to eliminate the extra
.B groff
processing pass,
which is required to generate a table of contents,
and relocate it to the start of the PDF document,
when processing any document which lacks an automatically
generated table of contents.
.TP
.BI \-\-pdf\-output= name
Specifies the name to be used for the resultant PDF document;
if unspecified, the PDF output is written to standard output.
A future version of
.B pdfroff
may use this option,
to encode the document name in a generated reference dictionary.
.TP
.BI \-\-reference\-dictionary= name
Specifies the name to be used for the generated reference dictionary file;
if unspecified, the reference dictionary is created in a temporary file,
which is deleted when
.B pdfroff
completes processing of the current document.
This option
.I must
be specified, if it is desired to save the reference dictionary,
for use in references placed in other PDF documents.
.TP
.B \-\-report\-progress
Causes
.B pdfroff
to display an informational message on standard error,
at the start of each
.B groff
processing pass.
.TP
.BI \-\-stylesheet= name
Specifies the name of an
.IR "input file" ,
to be used as a style sheet for formatting of content,
which is to be placed
.I before
the table of contents,
in the formatted PDF document.
.TP
.B \-\-version
Causes
.B pdfroff
to display a version identification message.
The entire command line is then passed transparently to
.BR groff ,
in a
.I one
pass operation
.IR only ,
in order to display the associated
.B groff
version information, before exiting.
.
.\" --------------------------------------------------------------------
.
.SH ENVIRONMENT
The following environment variables may be set, and exported,
to modify the behaviour of
.BR pdfroff .
.TP
.B GROFF_TMPDIR
Identifies the directory in which
.B pdfroff
should create temporary files.
If
.B GROFF_TMPDIR
is
.I not
specified, then the variables
.BR TMPDIR ,
.B TMP
and
.B TEMP
are considered in turn, as possible temporary file repositories.
If none of these are set, then temporary files will be created
in the current directory.
.TP
.B GROFF_GHOSTSCRIPT_INTERPRETER
Specifies the program to be invoked, when
.B pdfroff
converts
.B groff
PostScript output to PDF.
If
.B GROFF_GHOSTSCRIPT_INTERPRETER
is not specified, then
.B pdfroff
will search the process
.BR PATH ,
looking for a program with any of the well known names
for the GhostScript interpreter;
if no GhostScript interpreter can be found,
.B pdfroff
will abort.
.TP
.B GROFF_AWK_INTERPRETER
Specifies the program to be invoked, when
.B pdfroff
is extracting reference dictionary entries from a
.B groff
intermediate message stream.
If
.B GROFF_AWK_INTERPRETER
is not specified, then
.B pdfroff
will search the process
.BR PATH ,
looking for any of the preferred programs, `gawk', `mawk', `nawk'
and `awk', in this order;
if none of these are found,
.B pdfroff
will issue a warning message, and continue processing;
however, in this case, no reference dictionary will be created.
.TP
.B OSTYPE
Typically defined automatically by the operating system,
.B OSTYPE
is used on Microsoft Win32/MS\(hyDOS platforms
.IR only ,
to infer the default
.B PATH_SEPARATOR
character,
which is used when parsing the process
.B PATH
to search for external helper programs.
.TP
.B PATH_SEPARATOR
If set,
.B PATH_SEPARATOR
overrides the default separator character,
(':' on POSIX/UNIX systems,
inferred from
.B OSTYPE
on Microsoft Win32/MS\(hyDOS),
which is used when parsing the process
.B PATH
to search for external helper programs.
.TP
.B SHOW_PROGRESS
If this is set to a non-empty value, then
.B pdfroff
will always behave as if the
.B \-\-report\-progress
option is specified, on the command line.
.
.\" --------------------------------------------------------------------
.
.SH FILES
Input and output files for
.B pdfroff
may be named according to any convention of the user's choice.
Typically, input files may be named according to the choice of the
principal formatting macro package, e.g.,
.IB file .ms
might be an input file for formatting using the
.B ms
macros
.RB ( s.tmac );
normally, the final output file should be named
.IB file .pdf\c
\&.
.P
Temporary files, created by
.BR pdfroff ,
are placed in the directory specified by environment variables (see
section
.BR ENVIRONMENT ),
and named according to the convention
.BI pdf $$ .*\c
\&, where
.I $$
is the standard shell variable representing the process ID of the
.B pdfroff
process itself, and
.I *
represents any of a number of extensions used by
.B pdfroff
for temporary and intermediate files.
.

.
.SH SEE ALSO
See
.BR groff (@MAN1EXT@)
for the definitive reference to document formatting with
.BR groff .
Since
.B pdfroff
provides a superset of all
.B groff
capabilities,
.BR groff (@MAN1EXT@)
may also be considered to be the definitive reference to all
.I standard
capabilities of
.BR pdfroff ,
with this document providing the reference to
.BR pdfroff 's
extended features.
.P
While
.B pdfroff
imposes neither any restriction on, nor any requirement for,
the use of any specific
.B groff
macro package, a number of supplied macro packages,
and in particular those associated with the package
.BR pdfmark.tmac ,
are best suited for use with
.BR pdfroff
as the preferred formatter.
Detailed documentation on the use of these packages may be found,
in PDF format, in the reference guide
.BR "\*(lqPortable Document Format Publishing with GNU Troff\*(rq" ,
included in the installed documentation set as
