   7 # echo the current environment to stdout, filtering out redundant info.
   8 #
   9 # --exclude-init-phases causes pkg_nofetch and src_* phase functions to
  10 # be excluded from the output. These function are not needed for installation
  11 # or removal of the packages, and can therefore be safely excluded.
