botch is a collection of tools to create and analyze dependency graphs. This task is facilitated by a range of individual tools which use the deb822 and graphml formats to exchange information with each other. Also consider browsing the HTML based doc-base Manual at /usr/share/doc/botch/wiki/Home.html

The tools that botch ships allow one to:

 - analyze graphs
    - botch-calcportsmetric: calculate source package importance
    - botch-calculate-fas: calculate a feedback arc set
    - botch-find-fvs: calculate a feedback vertex set
    - botch-graph-difference: graph diff
    - botch-graph-info: show info about a buildgraph or sourcegraph
    - botch-partial-order: calculate the partial vertex order
    - botch-print-stats: find cycles, selfcycles, amount of cycles through
      edges, feedback arc and vertex set, strong articulation points and
    - botch-multiarch-interpreter-problem: find all arch:all packages that
      allow switching architectures
 - transform Packages and Sources control files
    - botch-latest-version: only keep the latest version
    - botch-bin2src: convert binary packages to their source packages

    - botch-filter-src-builds-for: filter a Sources file for the packages
      building for a certain architecture
 - create graphs of different types
    - botch-create-graph: create graph based on installation sets, strong
      dependency sets or dependency closures
    - botch-annotate-strong: add strong dependency information to a dependency
 - analysis of Packages and Sources control files
    - botch-packages-diff: create a diff between two Packages or Sources files
    - botch-ma-diff: diff two packages files for differences in their
      multiarch values
    - botch-apply-ma-diff: applies a multiarch diff as created by
    - botch-check-ma-same-versions: check if Multi-Arch:same versions are in
 - handling of botch-internal formats
    - botch-stat-html: turn the JSON output of botch-print-stats into human
      readable HTML
    - botch-droppable-diff: difference between two *.droppable files
    - botch-droppable-union: union of two *.droppable files
    - botch-checkfas: check which edges in the fas are not droppable
    - botch-fasofstats: extract feedback arc set from output of
    - botch-download-pkgsrc: download Packages and Sources
 - dose3 wrappers
    - botch-dose2html: turn the yaml output by dose-builddebcheck into html
    - botch-buildcheck-more-problems: a tool like dose-builddebcheck but
      return more than the first reason
    - botch-distcheck-more-problems: a tool like dose-distcheck but return
      more than the first reason
 - set operations on Packages or Sources files
    - botch-packages-difference: calculate the asymmetric set difference
    - botch-packages-intersection: calculate the set intersection
    - botch-packages-union: calculate the set union
 - create build orders
    - botch-build-fixpoint: find build order until dependency cycles occur
    - botch-build-order-from-zero: find a build order for a non-existing
    - botch-wanna-build-sortblockers: importance of source packages for ports
 - conversion of graphs
    - botch-buildgraph2srcgraph: converts a buildgraph into a srcgraph
    - botch-graphml2dot: converts graphml to dot

      dot format
    - botch-graph2text: for each vertex in a graph print a formatted line on
      standard output
 - shell scripts connecting the tools for meaningful operations
    - botch-cross: execute botch tools in the cross phase

      transitive essential.
 - extract regions from graphs
    - botch-graph-neighborhood: extract the neighborhood around a vertex
    - botch-extract-scc: extract all strongly connected components
    - botch-graph-ancestors: find all ancestors of a vertex in a graph in
      GraphML or dot format
    - botch-graph-descendants: find all descendants of a vertex in a graph in
      GraphML or dot format
    - botch-graph-shortest-path: find the shortest path(s) between two
      vertices of a graph in GraphML or dot format
    - botch-graph-sinks: find all sinks (vertices without successors) in a
      graph in GraphML or dot format
