+    (description
+     "The mblaze message system is a set of Unix utilities for processing and
+interacting with mail messages which are stored in maildir folders.
+
+Its design is roughly inspired by MH, the RAND Message Handling System, but it
+is a complete implementation from scratch.
+
+mblaze is a classic command line MUA and has no features for receiving or
+transferring messages; you can operate on messages in a local maildir spool,
+or fetch your messages using fdm(1), getmail(1), offlineimap(1), or similar
+utilities, and send it using dma(8), msmtp(1), sendmail(8), as provided by
+OpenSMTPD, Postfix, or similar.
+
+mblaze operates directly on maildir folders and doesn't use its own caches or
+databases.  There is no setup needed for many uses.  All utilities have been
+written with performance in mind.  Enumeration of all messages in a maildir is
+avoided unless necessary, and then optimized to limit syscalls.  Parsing
+message metadata is optimized to limit I/O requests.  Initial operations on a
+large maildir may feel slow, but as soon as they are in the file system cache,
+everything is blazingly fast.  The utilities are written to be memory
+efficient (i.e. not wasteful), but whole messages are assumed to fit into RAM
+easily (one at a time).")
