Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Check for ldc.conf next to the ldc binary before home and etc. The new search order is * current working directory * next to executable * user home directory * prefix/etc * prefix/etc/ldc * /etc * /etc/ldc
