NAME

       ftangle,fweave - WEB processors for C, C++, Fortran, Ratfor, and TeX

SYNOPSIS

       ftangle -|
                | [[-option] ...] src_file[.web] [change_file[.ch]]
       fweave --|

DESCRIPTION

       (This  man page is obsolete and is no longer maintained; please see `info fweb' for up-to-
       date and detailed tree-structured information.)

       FWEB is an extension of Knuth's WEB system to handle the languages C, C++,  Fortran  (both
       Fortran-77  and Fortran-90), Ratfor, and TeX.  The philosophy of WEB and all details about
       using FWEB may be found in the user manual fweb.tex, available on-line as the texinfo (GNU
       hypertext system) entry `info FWEB'.  See also

              http://w3.pppl.gov/~krommes/fweb_toc.html.

       An  initialization  file named .fweb (Unix sytems) or fweb.ini (personal computers) may be
       placed in your home directory.  (For Unix systems, that is the value of $HOME.   The  name
       can  be  overridden by the environment variable FWEB_INI.)  In this file can be placed any
       option that is allowed on the command line (one option per line).  If  the  option  begins
       with a hyphen, it is processed before the command line; if it begins with an ampersand, it
       is processed after the command line (rarely necessary); if it begins with neither,  it  is
       interpreted as a file name and processed after the command line.

       A  style  file  patterned  after the utility makeindex and named fweb.sty may be placed in
       your current directory.  (The directory can be  overridden  by  the  environment  variable
       FWEB_STYLE_DIR.)   This  file  is  used  to customize the appearance of the index and many
       other parameters controlling the operation of the processors.  See the  documentation  for
       detailed discussion.

       The following list just provides a very brief summary of the command-line options.  Please
       refer to the texinfo entry for more details.

       FWEB Options

       filename
               The first file name identifies the FWEB  source  file.   (If  the  name  does  not
               contain  a  period,  the extension .web is added automatically.)  If a second file
               name is present, it identifies the change file.  (If that name does not contain  a
               period, the extension .ch is added automatically.)  For an alternative approach to
               processing extensions, see the -e option.

               Print selected cross-reference information; the opposite of '-x'.

       -ya[a][nnnn]
               Override default for dynamic memory allocation. If nnnn is  omitted,  then  simply
               query the default.  The command '-y' with no argument queries everything.

               Redirect output.

       -=      Same as above (and easier to type).

       -#      Turn off comments about line numbers and modules in woven output.

       -+      Don't interpret the compound assignment operators in Fortran and Ratfor.

       -/      In  Fortran  and  Ratfor, make '//' denote the start of a short comment instead of
               concatenation.  (Use '' for concatenation.)

       -!      In Fortran and Ratfor, make '!'  denote the start of a short  comment  instead  of
               logical negation.

BUGS

       Please  send  bug  reports and suggestions to krommes@princeton.edu.  FWEB is a spare-time

       However, your input is very useful and much appreciated.

AUTHORS

       FWEB  was  written by John A. Krommes, Princeton University.  It is a substantial revision
       and update (more than 50% new) of version 0.5 of Silvio Levy's CWEB,  which  in  turn  was
       based  on Donald Knuth's original Pascal WEB.  The latter was designed for documenting and
       maintaining TeX.
