NAME

       cvsgraph - A CVS/RCS repository grapher

SYNOPSIS

       cvsgraph [options] [file]

DESCRIPTION

       CvsGraph generates images and image maps from CVS/RCS repository files.

OPTIONS

       -b     Deprecated, use -O'branch_dupbox=-1' for same functionality.

       -c file
              Read alternate config from file.

       -d level
              Enable debug mode at level. The amount of information is determined by a bitwise or
              of the following: 1=config  lexer,  2=config  parser,  4=rcsfile  lexer,  8=rcsfile
              parser,  16=rcsfile  structure.  The  level  argument  may  be in decimal, octal or
              hexadecimal format.

       -h     A brief description of possible options.

       -i     Generate an image map instead of an image.

       -I file
              Also write an image map to file. This can be useful if you want  to  generate  both
              image  and  image map simultaneously. This halves the total time spent on accessing
              the repository file because it is parsed only once.
              However, keeping track of auto-generated files can be a bit of a hack  if  used  in
              HTTP requests (unless you pass both image and HTML file in one HTTP stream).
              Note  1:  most time is used for the image-drawing routines (actually libgd), so you
              might want to think twice in CGI apps.
              Note 2: you can still use '-o' to specify an output file for the  image.   And,  if
              you  also  specify  '-i', then you'll get two image maps, for whatever purpose that
              might be.

       -k     Deprecated, use -O'auto_stretch=-1' for same functionality.
              This function is not stable.

       -M name
              Deprecated, use -O'map_name="AMapName"' for same functionality.

       -m mod Use mod as the CVS module.  This option overrides cvsmodule  in  the  configuration
              file.

       -O cfg_option=value[;opt=val[...]]
              Set cfg_option to value. Multiple -O are allowed as well as multiple options can be
              set simultaneously by  separating  them  with  ';'.   See  cvsgraph.conf(5)  for  a
              detailed list of options.  See also CONFIGURATION below.

       -o file
              Output to file. Otherwise, output is written to standard output.

       -q     Be quiet (i.e. no warnings)

       -r path
              Use path as the CVS root.  This option overrides cvsroot in the configuration file.

       -s     Deprecated, use -O'strip_untagged=-1' for same functionality.

       -S     Deprecated, use -O'strip_first_rev=-1' for same functionality.

       -u     Deprecated, use -O'upside_down=-1' for same functionality.

       -V     Print version and exit.

       -x {3,4,x}
              Set the HTML level of compliance for image maps. Use 3 for HTML 3.x, 4 for HTML 4.x
              and x for XHTML. Default is HTML 3.x compatibility.

       -[0-9] txt
              Use txt for expansion

CONFIGURATION

       CvsGraph starts with reading a configuration file. If the '-c'  option  is  given  on  the
       command line, then it is read. Otherwise, cvsgraph first looks for a configuration file in
       the  current  directory  using  ./cvsgraph.conf  and,  if  not  found,   tries   to   open
       /usr/local/etc/cvsgraph.conf.  Defaults  and  command  line  overrides  will be used if no
       configuration file can be opened. The format of the configuration  file  is  described  in
       cvsgraph.conf(5).  Configuration  parameters  entered  on  the  command  line  have always
       precedence over the  configuration  file.  Configuration  options  are  processed  in  the
       following order:
       - configuration file
       - '-O' command line options
       - other command line overrides (-bkMmrSsu)
       If  you  do  not  want  to  process  any  configuration  file, then you can set option ยด-c
       /dev/null', which will read an empty configuration file.

       The location of a repository file is determined by the  configuration  parameters  cvsroot
       and  cvsmodule  and  the  respective  command  line  options  '-r' and '-m'.  The cvsroot,
       cvsmodule and file are concatenated with separating '/' path-separators forming the  final
       location:
       <cvsroot>/<cvsmodule>/file
       No path-separator is appended if cvsroot and cvsmodule are empty strings. An error message
       is issued if the resulting path cannot be opened.  Note that cvsgraph does not attempt  to
       check  any  validity  of  the path components. This enables a user to open any file on the
       file-system by setting cvsroot and cvsmodule to empty strings.
       For example, cvsgraph -r '' -m '' ../myfile,v would try to open the file ../myfile,v. Note
       that  a  variety  of  possibilities  yield the same file and all have their advantages and
       drawbacks, which are mostly related  to  the  possible  use  of  the  parameters  in  text
       expansions.

       If  no file is given on the command line, then input is read from standard input. This can
       make  expansion  strings  somewhat  strange  looking,  but  they  are  composed  with  the
       information  available.  If no input file was given, then the input filename for expansion
       is set to <stdin>.

OUTPUT

       The output generated by cvsgraph can be either an image (default) or and  HTML  image  map
       ('-i' and '-I' options).
       Images  can have several formats, depending on the capabilities of the gd library on which
       the drawing is built. The configuration allows for GIF, PNG  or  JPEG  type  images.  Some
       recent  versions  of gd do no longer support GIF and PNG will be used instead. GIF support
       in gd was added again after the lzw patent expired.
       Generation of image maps conforms to the HTML standard and maps rectangular regions of the
       image where revisions and branches are drawn. Additionally, an extra rectangular region is
       generated between revisions to support diff generation.

FILES

       /usr/local/etc/cvsgraph.conf
              Configuration file read for default layout parameters.
