#
# Makefile fragment for packages with djb-style build machinery
#
# Common functions provided:
# * a boilerplate RESTRICTED clause
# * typical defaults for BUILD_TARGET and INSTALL_TARGET
# * typical values for conf-* files
# * replace inline definitions of errno with "#include <errno.h>"
#
# TODO:
# * centralize handling of third-party manpages
# * centralize MASTER_SITES and SITES_foo
# * centralize compiler hack for arm{,32}
# * common install script for compatibility with default conf-home pathnames
# * PKG_OPTIONS (default):
#     djbware-errno-hack (off)
#     djbware-pathname-compat (on)
#     inet6 (off)
#     pam (off)
# * set RESTRICTED automatically iff patches or other mods are applied
# * be unrestricted by default for bulk builds
