Support the characters of the current locale.

This allows specifying characters other than ASCII characters in the
'charset', 'prefix' and 'suffix' options.
For example, if you use a utf-8 locale, you can try to find a password
containing utf-8 characters.

-The beginning and the end of the password can be specified too.

+trying all the possible passwords. It is especially useful if you know
+something about the password (i.e. you forgot a part of your password but still
+remember most of it). Finding the password of a wallet without knowing
+anything about it would take way too much time (unless the password is really
+short and/or weak).

+There are command line options to specify:

 Sending a USR1 signal to a running bruteforce-wallet process makes it print
 progress info to standard error and continue.

 ## Limitations
 
+The program currently only works on unix-like POSIX systems (e.g. GNU/Linux).
+
 Different versions of BerkeleyDB are usually not compatible with each other.
 Therefore, for the program to work, you will have to check that the BerkeleyDB
 version you are using can read the databases created by the BerkeleyDB version
