NAME
       osage - filter for drawing clustered graphs

SYNOPSIS
       osage [-(G|N|E)name=value] [-Tlang] [-llibfile] [-ooutfile] [-O] [-P]
       [-v] [-V] [files]

DESCRIPTION
       osage draws clustered graphs. As input, it takes any graph in the dot
       format. It draws the graph recursively. At each level, there will be a
       collection of nodes and a collection of cluster subgraphs.  The
       internals of each cluster subgraph are laid out, then the cluster
       subgraphs and nodes at the current level are positioned relative to
       each other, treating each cluster subgraph as a node.

       At each level, the nodes and cluster subgraphs are viewed as rectangles
       to be packed together. At present, edges are ignored during packing.
       Packing is done using the standard packing functions. In particular,
       the graph attributes pack and packmode control the layout.  Each graph
       and cluster can specify its own values for these attributes.  Remember
       also that a cluster inherits its attribute values from its parent
       graph.

       After all nodes and clusters, edges are routed based on the value of
       the splines attribute.

OUTPUT FORMATS
       Osage uses an extensible plugin mechanism for its output renderers, so
       to see what output formats your installation of osage supports you can
       use ``osage -Txxx'' (where xxx is an unlikely format) and check the
       warning message.  Also, The plugin mechanism supports multiple
       implementations of the output formats.  To see what variants are
       available, use, for example: ``osage -Tpng:'' and to force a particular
       variant, use, for example: ``osage -Tpng:gd''

       Traditionally, osage supports the following: -Tps (PostScript), -Tsvg
       -Tsvgz (Structured Vector Graphics), -Tfig (XFIG graphics), -Tmif
       (FrameMaker graphics), -Thpgl (HP pen plotters), and -Tpcl (Laserjet
       printers), -Tpng -Tgif (bitmap graphics), -Tdia (GTK+ based diagrams),
       -Timap (imagemap files for httpd servers for each node or edge that has
       a non-null "href" attribute.), -Tcmapx (client-side imagemap for use in
       html and xhtml).  Additional less common or more special-purpose output
       formats can be found at
       http://www.graphviz.org/cvs/doc/info/output.html.)

       Alternative plugins providing support for a given output format can be
       found from the error message resulting from appending a ':' to the
       format. e.g. -Tpng: The first plugin listed is always the default.

GRAPH FILE LANGUAGE
       Here is a synopsis of the graph file language, normally using the
       extension .gv, for graphs:

       [strict] (graph|digraph) name { statement-list }
       Is the top level graph. If the graph is strict then multiple edges are
       not allowed between the same pairs of nodes.  If it is a directed
       graph, indicated by digraph, then the edgeop must be "->". If it is an
       undirected graph then the edgeop must be "--".  Statements may be:

       name=val;
       node [name=val];
       edge [name=val];
       Set default graph, node, or edge attribute name to val.  Any subgraph,
       node, or edge appearing after this inherits the new default attributes.

       n0 [name0=val0,name1=val1,...]; Creates node n0 (if it does not already
       exist) and sets its attributes according to the optional list.

       n0 edgeop n1 edgeop ... edgeop nn [name0=val0,name1=val1,...];
       Creates edges between nodes n0, n1, ..., nn and sets their attributes
       according to the optional list.  Creates nodes as necessary.

       [subgraph name] { statement-list }
       Creates a subgraph.  Subgraphs may be used in place of n0, ..., nn in
       the above statements to create edges.  [subgraph name] is optional; if
       missing, the subgraph is assigned an internal name.

       Comments may be /*C-like*/ or //C++-like.


       Attribute names and values are ordinary (C-style) strings.  The
       following sections describe attributes that control graph layout.


GRAPH ATTRIBUTES
       size="x,y" sets bounding box of drawing in inches.

       page="x,y" sets the PostScript pagination unit.

       ratio=f sets the aspect ratio to f which may be a floating point
       number, or one of the keywords fill, compress, or auto.

       pagedir=[TBLR][TBLR] sets the major and minor order of pagination.

       rotate=90 sets landscape mode.  (orientation=land is backward
       compatible but obsolete.)

       center=n a non-zero value centers the drawing on the page.

       layers="id:id:id:id" is a sequence of layer identifiers for overlay
       diagrams.  The PostScript array variable layercolorseq sets the
       assignment of colors to layers. The least index is 1 and each element
       must be a 3-element array to be interpreted as a color coordinate.

       color=colorvalue sets foreground color (bgcolor for background).

       href="url" the default url for image map files; in PostScript files,
       the base URL for all relative URLs, as recognized by Acrobat Distiller
       3.0 and up.

       URL="url" ("URL" is a synonym for "href".)

       stylesheet="file.css" includes a reference to a stylesheet in -Tsvg and
       -Tsvgz outputs.  Ignored by other formats.

       splines. If set to true, edges are drawn as splines.  If set to
       polyline, edges are drawn as polylines.  If set to ortho, edges are
       drawn as orthogonal polylines.  In all of these cases, the nodes may
       not overlap.  If splines=false or splines=line, edges are drawn as line
       segments.  The default is false.


NODE ATTRIBUTES
       height=d or width=d sets minimum height or width.  Adding
       fixedsize=true forces these to be the actual size (text labels are
       ignored).

       shape=record polygon epsf builtin_polygon
       builtin_polygon is one of: plaintext ellipse oval circle egg triangle
       box diamond trapezium parallelogram house hexagon octagon note tab
       box3d component.  (Polygons are defined or modified by the following
       node attributes: regular, peripheries, sides, orientation, distortion
       and skew.)  epsf uses the node's shapefile attribute as the path name
       of an external EPSF file to be automatically loaded for the node shape.

       label=text where text may include escaped newlines \n, \l, or \r for
       center, left, and right justified lines.  The string '\N' value will be
       replaced by the node name.  The string '\G' value will be replaced by
       the graph name.  Record labels may contain recursive box lists
       delimited by { | }.  Port identifiers in labels are set off by angle
       brackets < >.  In the graph file, use colon (such as, node0:port28).

       fontsize=n sets the label type size to n points.

       fontname=name sets the label font family name.

       color=colorvalue sets the outline color, and the default fill color if
       style=filled and fillcolor is not specified.

       fillcolor=colorvalue sets the fill color when style=filled.  If not
       specified, the fillcolor when style=filled defaults to be the same as
       the outline color.

       fontcolor=colorvalue sets the label text color.

       A colorvalue may be "h,s,v" (hue, saturation, brightness) floating
       point numbers between 0 and 1, or an X11 color name such as white black
       red green blue yellow magenta cyan or burlywood, or a "#rrggbb" (red,
       green, blue, 2 hex characters each) value.

       style=filled solid dashed dotted bold invis or any Postscript code.

       layer=id or id:id or "all" sets the node's active layers.  The empty
       string means no layers (invisible).

       The following attributes apply only to polygon shape nodes:

       regular=n if n is non-zero then the polygon is made regular, i.e.
       symmetric about the x and y axis, otherwise the polygon takes on the
       aspect ratio of the label.  builtin_polygons that are not already
       regular are made regular by this attribute.  builtin_polygons that are
       already regular are not affected (i.e.  they cannot be made
       asymmetric).

       peripheries=n sets the number of periphery lines drawn around the
       polygon.  This value supersedes the number of periphery lines of
       builtin_polygons.

       sides=n sets the number of sides to the polygon. n<3 results in an
       ellipse.  This attribute is ignored by builtin_polygons.

       orientation=f sets the orientation of the first apex of the polygon
       counterclockwise from the vertical, in degrees.  f may be a floating
       point number.  The orientation of labels is not affected by this
       attribute.  This attribute is added to the initial orientation of
       builtin_polygons.

       distortion=f sets the amount of broadening of the top and narrowing of
       the bottom of the polygon (relative to its orientation).  Floating
       point values between -1 and +1 are suggested.  This attribute is
       ignored by builtin_polygons.

       skew=f sets the amount of right-displacement of the top and left-
       displacement of the bottom of the polygon (relative to its
       orientation).  Floating point values between -1 and +1 are suggested.
       This attribute is ignored by builtin_polygons.

       href="url" sets the url for the node in imagemap, PostScript and SVG
       files.  The substrings '\N' and '\G' are substituted in the same manner
       as for the node label attribute.  Additionally the substring '\L' is
       substituted with the node label string.

       URL="url" ("URL" is a synonym for "href".)

       target="target" is a target string for client-side imagemaps and SVG,
       effective when nodes have a URL.  The target string is used to
       determine which window of the browser is used for the URL.  Setting it
       to "_graphviz" will open a new window if it doesn't already exist, or
       reuse it if it does.  If the target string is empty, the default, then
       no target attribute is included in the output.  The substrings '\N' and
       '\G' are substituted in the same manner as for the node label
       attribute.  Additionally the substring '\L' is substituted with the
       node label string.

       tooltip="tooltip" is a tooltip string for client-side imagemaps and
       SVG, effective when nodes have a URL.  The tooltip string defaults to
       be the same as the label string, but this attribute permits nodes
       without labels to still have tooltips thus permitting denser graphs.
       The substrings '\N' and '\G' are substituted in the same manner as for
       the node label attribute.  Additionally the substring '\L' is
       substituted with the node label string.



EDGE ATTRIBUTES
       label=text where text may include escaped newlines \n, \l, or \r for
       centered, left, or right justified lines.  If the substring '\T' is
       found in a label it will be replaced by the tail_node name.  If the
       substring '\H' is found in a label it will be replaced by the head_node
       name.  If the substring '\E' value is found in a label it will be
       replaced by: tail_node_name->head_node_name If the substring '\G' is
       found in a label it will be replaced by the graph name.  or by:
       tail_node_name--head_node_name for undirected graphs.

       fontsize=n sets the label type size to n points.

       fontname=name sets the label font family name.

       fontcolor=colorvalue sets the label text color.

       style=solid dashed dotted bold invis

       color=colorvalue sets the line color for edges.

       color=colorvaluelist a ':' separated list of colorvalue creates
       parallel edges, one edge for each color.

       dir=forward back both none controls arrow direction.

       tailclip,headclip=false disables endpoint shape clipping.

       href="url" sets the url for the node in imagemap, PostScript and SVG
       files.  The substrings '\T', '\H', '\E' and '\G' are substituted in the
       same manner as for the edge label attribute.  Additionally the
       substring '\L' is substituted with the edge label string.

       URL="url" ("URL" is a synonym for "href".)

       target="target" is a target string for client-side imagemaps and SVG,
       effective when edges have a URL.  If the target string is empty, the
       default, then no target attribute is included in the output.  The
       substrings '\T', '\H', '\E' and '\G' are substituted in the same manner
       as for the edge label attribute.  Additionally the substring '\L' is
       substituted with the edge label string.

       tooltip="tooltip" is a tooltip string for client-side imagemaps
       effective when edges have a URL.  The tooltip string defaults to be the
       same as the edge label string.  The substrings '\T', '\H', '\E' and
       '\G' are substituted in the same manner as for the edge label
       attribute.  Additionally the substring '\L' is substituted with the
       edge label string.

       arrowhead,arrowtail=none, normal, inv, dot, odot, invdot, invodot, tee,
       empty, invempty, open, halfopen, diamond, odiamond, box, obox, crow.

       arrowsize (norm_length=10,norm_width=5,
       inv_length=6,inv_width=7,dot_radius=2)

       headlabel,taillabel=string for port labels.
       labelfontcolor,labelfontname,labelfontsize for head and tail labels.
       The substrings '\T', '\H', '\E' and '\G' are substituted in the same
       manner as for the edge label attribute.  Additionally the substring
       '\L' is substituted with the edge label string.

       headhref="url" sets the url for the head port in imagemap, PostScript
       and SVG files.  The substrings '\T', '\H', '\E' and '\G' are
       substituted in the same manner as for the edge label attribute.
       Additionally the substring '\L' is substituted with the edge label
       string.

       headURL="url" ("headURL" is a synonym for "headhref".)

       headtarget="headtarget" is a target string for client-side imagemaps
       and SVG, effective when edge heads have a URL.  The headtarget string
       is used to determine which window of the browser is used for the URL.
       If the headtarget string is empty, the default, then headtarget
       defaults to the same value as target for the edge.  The substrings
       '\T', '\H', '\E' and '\G' are substituted in the same manner as for the
       edge label attribute.  Additionally the substring '\L' is substituted
       with the edge label string.

       headtooltip="tooltip" is a tooltip string for client-side imagemaps
       effective when head ports have a URL.  The tooltip string defaults to
       be the same as the headlabel string.  The substrings '\T', '\H', and
       '\E' are substituted in the same manner as for the edge label
       attribute.  Additionally the substring '\L' is substituted with the
       edge label string.

       tailhref="url" sets the url for the tail port in imagemap, PostScript
       and SVG files.  The substrings '\T', '\H', '\E' and '\G' are

       string.

       tailURL="url" ("tailURL" is a synonym for "tailhref".)

       tailtarget="tailtarget" is a target string for client-side imagemaps
       and SVG, effective when edge tails have a URL.  The tailtarget string
       is used to determine which window of the browser is used for the URL.
       If the tailtarget string is empty, the default, then tailtarget
       defaults to the same value as target for the edge.  The substrings
       '\T', '\H', '\E' and '\G' are substituted in the same manner as for the
       edge label attribute.  Additionally the substring '\L' is substituted
       with the edge label string.

       tailtooltip="tooltip" is a tooltip string for client-side imagemaps
       effective when tail ports have a URL.  The tooltip string defaults to
       be the same as the taillabel string.  The substrings '\T', '\H', '\E'
       and '\G' are substituted in the same manner as for the edge label
       attribute.  Additionally the substring '\L' is substituted with the
       edge label string.

       labeldistance and port_label_distance set distance; also labelangle (in
       degrees CCW)

       decorate draws line from edge to label.

       samehead,sametail aim edges having the same value to the same port,
       using the average landing point.

       string means no layers (invisible).


       (neato-specific attributes)
       w=f sets the weight (spring constant) of an edge to the given floating
       point value.  The default is 1.0; greater values make the edge tend
       more toward its optimal length.

       len=f sets the optimal length of an edge.  The default is 1.0.

COMMAND LINE OPTIONS
       -G sets a default graph attribute.
       -N sets a default node attribute.
       -E sets a default edge attribute.  Example: -Gsize="7,8" -Nshape=box
       -Efontsize=8

       -lfile loads custom PostScript library files.  Usually these define
       custom shapes or styles.  If -l is given by itself, the standard
       library is omitted.

       -Tlang sets the output language as described above.

       -O automatically generate output filenames based on the input filename
       and the -T format.

       -v (verbose) prints various information useful for debugging.

       -V (version) prints version information and exits.

       -? prints the usage and exits.
