 ## Behavior

-- [ ] add checking for conflicting command-line options
-- [ ] support for deletion of messages after being matched and displayed
+- [x] add checking for conflicting command-line options
 - [x] ignore .overview when grepping Gnus folders
 - [x] inverted matching
 - [x] recursive search through directories
 - [x] writing selected messages to a new folder
 - [x] deleting selected messages
-- [ ] basic time and date matching
-- [ ] more advanced time and date matching, with strings such as "yesterday"

+- [ ] support for deletion of messages after being matched and displayed
+- [ ] basic time and date matching
+- [ ] more advanced time and date matching, with strings such as "yesterday"
+- [ ] Remove the option to recursively traverse directories and instruct the users to run mboxgrep in conjuction with find(1) instead.
 
 ## File formats, encodings and standards
 
-- [ ] MIME support
-- [ ] support for GnuPG
+- [x] migrate to pcre2, as pcre is obsolete
 - [x] support for compressed mbox folders
 - [x] support for bzip2 compression
+- [ ] use a more modern hash function than MD5
+- [ ] MIME support
+- [ ] support for GnuPG
 - [ ] support for XZ-format compression
 - [ ] support for mail folder conversion
-- [ ] use a more modern hash function than MD5
 - [ ] improve error detection when a directory is not a Maildir or MH folder
 - [ ] document criteria for folder format detection
+- [ ] Maildir: check if an atomic rename() fails. This could be caused if "new" and "cur" subdirectories are not on the same filesystem, for example.
 
 ## Miscellaneous
 
 - [x] write Texinfo documentation
+- [x] provide possibility to use flock() instead of fcntl()
 - [ ] configuration files
 - [ ] make use of lockfile library
 - [ ] make use of Solaris' maillock library

-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as
-## well.  hp depmode also adds that space, but also prefixes the VPATH
