# This file handles about all the preparation aspects for
# `config.status': registering the configuration files, the headers,
# the links, and the commands `config.status' will run.  There is a
# little mixture though of things actually handled by `configure',
# such as running the `configure' in the sub directories.  Minor
# detail.
#
# There are two kinds of commands:
#
# COMMANDS:
#
#   They are output into `config.status' via a quoted here doc.  These
#   commands are always associated to a tag which the user can use to
#   tell `config.status' what are the commands she wants to run.
#
# INIT-CMDS:
#
#   They are output via an *unquoted* here-doc.  As a consequence $var
#   will be output as the value of VAR.  This is typically used by
#   `configure' to give `config.status' some variables it needs to run
#   the COMMANDS.  At the difference of COMMANDS, the INIT-CMDS are
#   always run.
#
#
# Honorable members of this family are AC_CONFIG_FILES,
# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS.  Bad boys
# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
# arguments.  False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS
# and AC_CONFIG_AUX_DIR.  Cousins are AC_CONFIG_COMMANDS_PRE and
# AC_CONFIG_COMMANDS_POST.
