- can be implemented as component independent (no fwk.perameters)

1. <fetch libname>
  - macro
  : extracts information regarding libname

2. <ancall -fetch>
  : is called with parameters from 1.
  : do split of the control flow on the base of parameters (is.zip, is.jar, ...)

  1. <target fetch-jar>
    : downloads jar file
    : checks for file presence

    1. <antcall -do-download>
      : executes if target lib file does not exist in lib dir

    2. <do-download libname>
      - macro
      : downloads jar to temp dir, checksum, move to lib dir

  2. <target fetch-zip>
    : downloads zip file, extracts jar lib, places it to lib dir
    : checks for file presence

    1. <antcall -do-download>
      : executes if target lib file does not exist in lib dir

    2. <do-download libname>
      - macro
      : downloads zip to temp dir, checksum, unzip jar lib, move lib to lib dir
