(i've also noticed that an "stg pop / stg push" sequence causes 'make' to rebuild everything -- possibly due to the same reason?) am i all wet here? --------------030407040802020206070805 Content-Type: text/x-vcard; charset=utf-8; name="cel.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="cel.vcf" begin:vcard fn:Chuck Lever n:Lever;Charles org:Network Appliance, Incorporated;Linux NFS Client Development adr:535 West William Street, Suite 3100;;Center for Information Technology Integration;Ann Arbor;MI;48103-4943;USA email;internet:cel@citi.umich.edu title:Member of Technical Staff tel;work:+1 734 763 4415 tel;fax:+1 734 763 4434 tel;home:+1 734 668 1089 x-mozilla-html:FALSE url:http://www.monkey.org/~cel/ version:2.1 end:vcard --------------030407040802020206070805--
