    <cough>Not everywhere sh=bash; this is true for OpenBSD, where sh=ksh. :-)

Sure.  I didn't mean to type "bash" (I copied the text from another file
where I use bash).  The install script doesn't need bash in particular,
anything sh-compatible should be fine.

Thanks,

P.S. Last I knew, even when sh==bash, it doesn't really ==bash.  Certain
features and option settings are changed and/or turned off for sh
compatibility, depending on argv[0], so the behavior of /bin/sh and
/bin/bash is not always the same even if it's the same binary.  But
maybe this is no longer the case, I haven't checked in a long time.
