NAME

       troffcvt - troff-to-XXX converter

SYNTAX

       troffcvt [ options ] file ...

DESCRIPTION

       troffcvt  converts  troff input into an intermediate form that is easier to interpret than
       raw troff language.  This intermediate form  can  then  be  used  by  postprocessors  like
       tc2html or tc2rtf to produce final output in a target format such as HTML or RTF.

       troffcvt understands the options listed below.  Except as noted, options must be specified
       before the first input file named on the command line.

       -A     Normally, troffcvt reads the default action file before reading any action or macro
              files  named  on  the command line using the -a or -m options.  If -A is specified,
              troffcvt doesn't read the default action file.  This option is rarely used, but  it
              can be helpful when you want to try out a modified default file.

       -afile, -a file
              Read the given action file.  -a may also be specified in the input file part of the
              argument list.

       -C     Turn  on  groff-style  compatibility  mode.   Specifically,  this  option  disables
              recognition of long (> 2 character) request and macro names, and special character,
              register, string, font, and macro argument references of the forms \[xxx], \n[xxx],
              \*[xxx], \f[xxx], and \$[nnn].

              If  -C  is  specified, compatibility mode is turned on when the first input file is
              about to be read.  (Macro packages specified with -m may turn on compatibility mode
              themselves,  of  course.   However,  compatibility  mode is always turned off while
              action files are read.)

       -dN, -d N
              Turn on debugging flag N.  The flags are  listed  in  troffcvt.h.   If  -d  is  not
              followed by a number, all flags are turned on.

       -l     Generate  \line  controls  in  the output to indicate the point at which each input
              line was read.  These controls have the following form:
              \line filename linenumber
       where filename is the current input filename and linenumber is the current input  line  in
       that file.

       -mxx   Read the given macro package (e.g., -man, -ms) before the input files are read.

       -rN, -r N
              Specify a resolution of N units per inch.  The default is 432 units/inch.

       -tformatter-type, -t formatter-type
              Specify  a  formatter  type that troffcvt should try to act like.  Valid formatter-
              type values are:

              nroff  Act like nroff

              troff  Act like troff

              This option has little effect on troffcvt's behavior other than  to  determine  the
              result of the .if t and .if n conditionals.

       troffcvt finds action files by looking in the following locations:

       ·      The current directory.

       ·      The troffcvt library directory, /usr/share/troffcvt.

       troffcvt finds macro packages by looking in the following locations:

       ·      The  directories  named  by  the  TROFFCVT_TMAC_PATH  environment variable, if that
              variable is set.  TROFFCVT_TMAC_PATH consists of one or more directories, separated
              by colons.

       ·      The  directory named by the TROFFCVT_LIB_DIR environment variable, if that variable
              is set.

       ·      The current directory.

       ·      The compiled-in troffcvt library directory /usr/share/troffcvt.  This allows you to
              override  a  system  macro  package  by placing a different version in the troffcvt
              library.

       ·      The system macro directory (e.g., /usr/lib/tmac or /usr/share/groff/tmac).

       Macro and action files specified with -m  and  -a  prior  to  the  first  input  file  are
       processed  in  order  before  the first input file is read.  Once the initial options have
       been read and processed, troffcvt reads the input files, or the standard input if no files
       are  read.   The  name - may be used to refer explicitly to the standard input.  -a may be
       used to intersperse action files with input files in this part of the argument list.   For
       example:
              % troffcvt -ms mymacros -a tc.mymacros mydoc

DIAGNOSTICS

       If troffcvt cannot open a macro file, you will see this message:
              cannot open macro file -mxx
       This message is fatal.

       If troffcvt cannot open an action file, you will see this message:
              cannot open action file <xx>
       This  message usually indicates a problem, but is not fatal (except for the default action
       file actions, which must be available for troffcvt to do anything at all).  If  you  still
       get  reasonable  output,  you can ignore it.  To make the message go away, create an empty
       file named xx in any of the directories in which troffcvt looks for action files.  If  you
       don't  get reasonable output, then a non-empty file needs to be created that redefines the
       macros that confuse troffcvt.
