====== tasks ======

===== Bitbake tasks =====

  * ''fetch'' If needed, make local copy of remote sources (bz2, git, svn,  ...).
  * ''unpack'' prepare source of package in work directory (bz2 - unpack, git -   clone from local copy, etc)
  * ''patch'' apply all *.patch files from SRC_URI
  * ''configure''
  * ''compile''
  * ''install''
  * ''package'' split installed on fake sysroot files into separate packages:
     * main package or library (package_name)
     * debugging symbols (package_name-dbg)
     * documentation (package_name-doc)
     * locales (package_name-locale)
     * development headers (package_name-dev)

  * ''clean''
  * ''cleanstate'' remove output and SSTATE cache files for given package

===== remove tasks =====

Usefull to remove default tasks (configure + compile) for copy-only packages.

3 method possible:

  - **deltask** - completely removes tasks and its dependency (use with care!)
  - **NOP** task - define tasks as empty: ''do_compile() { : }''. Old way to "disable", tasks are still executed so it generate overhead.
  - **do_task[noexec]** - is new way to cleanly disable task. No overhead, task is skipped.

<code>
do_fetch[noexec] = "1"
do_unpack[noexec] = "1"
do_patch[noexec] = "1"
do_configure[noexec] = "1"
do_compile[noexec] = "1"
