/*
- This command is a dumb mail indexer. It can either (1) scan
- directories containing mbox files, and create a db file containing
- for each mail a list of fields computed from the header, or (2)
- read such a db file and get all the mails matching regexp-defined
- conditions on the fields.
+ mymail is a simple mail indexer. It can:
+
+ (1) scan mbox files, and create a db file containing for each mail a
+ list of fields computed from its header.
+
+ (2) read such a db file, gets all the mails matching regexp-defined
+ conditions on the fields, and generates a resulting mbox file.
It is low-tech, simple, light and fast.
