Hi,
I might be missing something, but once you've found the binary, why not
check the version with a simple shell script, something along the lines of:
MAKEINFO_VERSION=`$MAKEINFO --version|head -n1|sed -ne 's/.*
\([0-9]\+\)\.[0-9]\+.*/\1/p'`
if test $MAKEINFO_VERSION -lt 5
then
# Version less than 5, error handling goes here?
fi
Where MAKEINFO is the detected makeinfo binary. It does assume that the
--version output of makeinfo doesn't change too much between releases,
could remove 'head -n1" and change sed to 's/^makeinfo .*
\([0-9]\+\)\.[0-9]\+.*/\1/p' too make it slightly more robust (see
'makeinfo --version' output).
Let me know if this an acceptable solution and I can submit a pull request
:)
