comparison servlet/src/digilib/io/AliasingDocuDirCache.java @ 259:beed92ee6022

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Servlet version 1.21b1 - directory indexing got faster but less safe (configurable by "safe-dir-index") - mo=rawfile supplies filename - DigilibConfig takes File parameters - some SerialVersionUIDs (suggested by Eclipse)
