This snapshot was built with the version 18.104.22.168 of the "directory"
package taken from the GHC 6.10 branch. The reason for this: head
version of System.Directory became incompatible with Hugs, likely
after the NHC integration patch. This patch was not applied to the GHC
6.10 branch before tagging 22.214.171.124. Ther rest of packages are from the
head, plus several packages necessary to use the Yhc Core tools were
added to the snapshot.
