erlang-tools 1:20.2.2+dfsg-1ubuntu2 (amd64 binary) in ubuntu bionic

 The Tools application contains a number of stand-alone tools, which are
 useful when developing Erlang programs.
 .
  cover - A coverage analysis tool for Erlang.
  cprof - A profiling tool that shows how many times each function
    is called. Uses a kind of local call trace breakpoints containing
    counters to achieve very low runtime performance degradation.
  eprof - A time profiling tool; measures how time is used in Erlang
    programs. Predecessor of fprof (see below).
  fprof - Another Erlang profiler; measures how time is used in Erlang
    programs. Uses trace to file to minimize runtime performance
    impact, and displays time for calling and called functions.
  instrument - Utility functions for obtaining and analyzing resource
    usage in an instrumented Erlang runtime system.
  make - A make utility for Erlang similar to UNIX make.
  tags - A tool for generating Emacs TAGS files from Erlang source
    files.
  xref - A cross reference tool. Can be used to check dependencies
    between functions, modules, applications and releases.
