NAME

       botch-graph-shortest-path - find the shortest path(s) between two vertices of a graph in
       GraphML or dot format

SYNOPSIS

       botch-graph-shortest-path [options] [ingraph] [outgraph] --source SOURCE [SOURCE ...]
       --target TARGET [TARGET ...]

DESCRIPTION

       Extract the subgraph of the shortest path between two specific nodes in the input graph.

       The --target and --source options are mandatory. Since they can take more than one
       argument, they have to come after the positional arguments.

       If either (or both) of the positional arguments is/are omitted, then read GraphML or dot
       from standard input and/or write GraphML or dot to standard output, respectively.  Passing
       a '-' as either argument, explicitly specifies to read the input from standard input and
       write the output to standard output, respectively.

       The input graph type will be determined automatically. If the output graph is given as a
       filename, then the output type will be GraphML if the filename ends with .xml and dot if
       the filename ends with .dot. If the output is done on standard output then it will happen
       in the same format as the input graph.

OPTIONS

       -h, --help
           Display help.

       --target=TARGET [TARGET ...]
           key:value pairs to match the target vertex

           The special key "__ID__" allows one to select the unique vertex identifier.

       --source=SOURCE [SOURCE ...]
           key:value pairs to match the source vertex

           The special key "__ID__" allows one to select the unique vertex identifier.

       --all
           instead of finding an arbitrary shortest path, find all shortest paths

       -v, --verbose
           Be verbose.

EXAMPLE

       Extract the subgraph of the shortest path from a certain version of the build-essential
       binary vertex to a certain version of the ghc source vertex.

         botch-graph-shortest-path --source name:build-essential version:11.7 type:bin --target name:ghc version:7.8.4-8 type:src < in.xml > out.xml

       or giving input and output as positional arguments:

         botch-graph-shortest-path in.xml out.xml --source name:build-essential version:11.7 type:bin --target name:ghc version:7.8.4-8 type:src
