I'm trying to write a package to be configured with metaconfig.  I did fix
metaconfig 2 to work with perl 3 (044) (I no longer get syntax errors, but
I might not have fixed everything that needed fixing.)

I created a test "package" consisting of just one *.U unit and one *.SH
file (included below).  Metaconfig runs to completion but then I'm left
with empty Configure and config.h.SH files.  This is the output of metaconfig:

$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle
$! nulled, predecessor circle

This is mytest.U:

if test $var1 -gt 1; then

$echo $n "$q_no3$c"
. myread var3

$echo $n "$q_no4$c"
. myread c1

$echo $n "$q_no5$c"
. myread c2


And this is mytest.c.SH:

case $CONFIG in
'')
    if test ! -f config.sh; then
	ln ../config.sh . || \
	ln ../../config.sh . || \
	ln ../../../config.sh . || \
	(echo "Can't find config.sh."; exit 1)
    fi
    . config.sh
    ;;
esac
: This forces SH files to create target in same directory as SH file.
: This is so that make depend always knows where to find SH derivatives.
case "$0" in
*/*) cd `expr X$0 : 'X\(.*\)/'` ;;
esac
echo "Extracting fdmtron.c (with variable substitutions)"
: This section of the file will have variable substitutions done on it.
: Move anything that needs config subs from !NO!SUBS! section to !GROK!THIS!.

$spitshell >mytest.c <<!GROK!THIS!
/*

/************************************************************************/

{

if test $var2 ; then
  $spitshell >>mytest.c <<!GROK!THIS!
  $c1 = $var3 |= $c2;
}
!GROK!THIS!
else
$spitshell >>mytest.c <<!GROK!THIS!
  $c1 |= $c2;
}
!GROK!THIS!
fi
: In the following dollars and backticks do not need the extra backslash.
$spitshell >>mytest.c <<'!NO!SUBS!'
!NO!SUBS!
chmod 755 mytest.c
$eunicefix mytest.c

Any solution, hint or even documentation for dist 3 would be most welcome.
What am I doing wrong?  This is driving me nuts!

Thanks in advance.  I'll post a summary of e-mail responses if there's
interest.
