mirko kiefer sent me I wrote a simple client for the Amazon Web Services in Node.js that allows you to do this kind of queries.

The best thing to do is to make the mailing list enforce trimming and quote- to original text fraction and reject top- and bottom-posts.

by stephane ducasse Nov. 1, 2010

Nov. 1, 2010

Gofer new squeaksource: 'XMLSupport'; package: 'XML-Parser'; load. raise error because of tests not present. Did I do something wrong? Then why the configuration load pastell? why this is squeakCommon? Does it work if this is in pharo? Why do we load SIXX in gemstone? This configuration looks like a mess. Can somebody fix that. core should load the parser sixx may be sixx pastell should load core and pastell Stef version105: spec <version: '1.0.5' imports: #('1.0.5-baseline' )> spec for: #'common' do: [ spec blessing: #stable. spec author: 'Alexandre Bergel'. spec timestamp: '10/5/2010 14:06'. ]. spec for: #'squeakCommon' do: [ spec package: 'XML-Parser' with: 'XML-Parser-AlexandreBergel.93'; package: 'Pastell' with: 'Pastell-Alexandre_Bergel.18'.]. spec for: #'gemstone' do: [ spec project: 'Grease Core' with: '1.0-rc'. spec package: 'XML-Parser' with: 'XML-Parser.g-DaleHenrichs.93'; package: 'SIXX' with: 'SIXX-NorbertHartl.171'.].
