-# @FUNCTION: filter_readonly_variables
-# @DESCRIPTION: [--filter-sandbox] [--allow-extra-vars]
-# Read an environment from stdin and echo to stdout while filtering variables
-# with names that are known to cause interference:
-#
-#   * some specific variables for which bash does not allow assignment
-#   * some specific variables that affect portage or sandbox behavior
-#   * variable names that begin with a digit or that contain any
-#     non-alphanumeric characters that are not be supported by bash
-#
-# --filter-sandbox causes all SANDBOX_* variables to be filtered, which
-# is only desired in certain cases, such as during preprocessing or when
-# saving environment.bz2 for a binary or installed package.
-#
-# --filter-features causes the special FEATURES variable to be filtered.
-# Generally, we want it to persist between phases since the user might
-# want to modify it via bashrc to enable things like splitdebug and
-# installsources for specific packages. They should be able to modify it
-# in pre_pkg_setup() and have it persist all the way through the install
-# phase. However, if FEATURES exist inside environment.bz2 then they
-# should be overridden by current settings.
-#
-# --filter-locale causes locale related variables such as LANG and LC_*
-# variables to be filtered. These variables should persist between phases,
-# in case they are modified by the ebuild. However, the current user
-# settings should be used when loading the environment from a binary or
-# installed package.
-#
-# --filter-path causes the PATH variable to be filtered. This variable
-# should persist between phases, in case it is modified by the ebuild.
-# However, old settings should be overridden when loading the
-# environment from a binary or installed package.
-#
-# ---allow-extra-vars causes some extra vars to be allowd through, such
-# as ${PORTAGE_SAVED_READONLY_VARS} and ${PORTAGE_MUTABLE_FILTERED_VARS}.
-#
-# In bash-3.2_p20+ an attempt to assign BASH_*, FUNCNAME, GROUPS or any
-# readonly variable cause the shell to exit while executing the "source"
-# builtin command. To avoid this problem, this function filters those
-# variables out and discards them. See bug #190128.
