| Well, I see two ways.
| 
| If you don't want to share the code between auto*.sh and config.status you
| can use short scripts and call them from auto*.sh, i.e.:
| 
| . @datadir@/prepare-env
| . @datadir@/mktmpdir ac
| 
| Another way is to use AC_SUBST_FILE. This way, acgeneral.m4 (but not other
| *.m4) becomes acgeneral.m4.in and has some code in AC_CONFIG_*S
| substituted from some files. The same code would be substituted in
| auto*.sh

Actually I was referring to factoring the source, not the output.
