.SH "NAME"
botch\-graph2text \- for each vertex in a graph print a formatted line on standard output
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.IP "\fBbotch\-graph2text\fR [options] [\fIingraph\fR] formatstring" 4
.IX Item "botch-graph2text [options] [ingraph] formatstring"
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Given a \fBformatstring\fR of the form \f(CW\*(C`{attr1} {attr2}...\*(C'\fR, print a line with
this format for every vertex in the graph, replacing \f(CW\*(C`{attr}\*(C'\fR placeholders
with the value of the attribute \f(CW"attr"\fR for that vertex. If no attribute with
name \f(CW"attr"\fR was found, then the placeholder \f(CW\*(C`{XXX}\*(C'\fR remains in the output
string. To write a literal opening or closing curly brace, type them twice,
respectively.  The special placeholder \f(CW\*(C`{_\|_ID_\|_}\*(C'\fR is replaced with the vertex
identifier.
.PP
If the positional arguments is omitted, then read GraphML or dot from standard
input.  Passing a '\-' as either argument, explicitly specifies to read the
input from standard input. The input graph type will be determined
automatically.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-h, \-\-help\fR" 4
.IX Item "-h, --help"
Display help.
.IP "\fB\-\-vertex=\fR\fI\s-1VERT\s0\fR" 4
.IX Item "--vertex=VERT"
This option picks the set of vertices that will be output. The \s-1VERT\s0 argument is
a key/value pair (separated by a colon) of a graph attribute and its value. By
default (without this option), all vertices of the graph are considered.
.Sp
The special key \f(CW\*(C`_\|_ID_\|_\*(C'\fR allows one to select the unique vertex identifier.
.Sp
This option can be specified more than once. The final set of vertices is
chosen such that all vertices match all key/value pairs. Multiple \fB\-\-vertex\fR
options thus form a logical conjunction (they are AND-ed together).
.IP "\fB\-v, \-\-verbose\fR" 4
.IX Item "-v, --verbose"
Be verbose.
.SH "EXAMPLE"
.IX Header "EXAMPLE"
