define Package/bash/description
  Bash is an sh-compatible command language interpreter that executes
  commands read from the standard input or from a file. Bash also
  incorporates useful features from the Korn and C shells (ksh and csh).
endef

# Bash detects and enables certain features by runtest simple piece of code
# which is not viable when doing cross compilation and default to no in many
# cases.  Grep for 'cross.compil' in aclocal.m4 and config-bot.h for details
#
# bash_cv_job_control_missing: Job control is needed for bash to be used as the
# default shell
#
# bash_cv_getcwd_malloc: The replacement by bash does not work well with
# overlayfs.  See "bash getcwd errors when running under OverlayFS"
# http://permalink.gmane.org/gmane.linux.embedded.yocto.general/25204
#
# bash_cv_dev_fd: The test is done on build system but OpenWrt currently does
# not have /dev/fd, it provides /proc/self/fd/ instead
#
# bash_cv_sys_named_pipes: Required for process substituion
