mairix - 0.24-2 main

mairix is a program for indexing and searching email messages stored
offline on your computer. mairix supports the Maildir, MH folders,
and mbox formats.
.
Some features:
.
* Indexing is fast. It runs incrementally on new messages - any
particular message only gets scanned once in the lifetime of the
index file.
.
* Searching is fast.
.
* The search mode populates a "virtual" maildir folder with symlinks
which point to the real messages. This folder can be opened as usual
in your mail program.
.
* Indexing and searching is based on words. The index file tabulates
which words occur in which parts (particular headers + body) of which
messages.
