2.3 2.4 ablfs ablfs-more legacy new_features trunk
Last change on this file since d8006a00 was de63126, checked in by Thomas Pegg <thomasp@…>, 15 years ago

Add configuration options for retry on connection refused, number of times to attemp to download a file, and timeout for wget invocation. Thanks to Tim Sarbin for the patch, slightly modified by me to accomodate a second set of wget calls.
