-c --wordcount <count> Number of words (default: 4)
-f --dictfile <dictfile> Dictionary file to use (default:
/usr/share/dict/american-english)
-l --minlen <count> Minimum word len (default: 5)
-m --maxlen <count> Maximum word len (default: 10)
-n --dontjump Use all words in the dict file, e.g.
if it is an original diceware list
-d --debug Enable debug output
-v --version Print program version
-h -? --help Print this help screen
=head1 DESCRIPTION
dicepwgen generates a diceware password using a dictionary
file. By default it uses pseudo random dice tosses, but
it is also possible to use real dices and enter the numbers
by using the option B<-t>, which is the most secure way
to generate diceware passwords.
The option B<-c> can be used to tweak the number of words
to output. The options B<-l> and B<-m> can be used to tweak
minimum and maximum word length.
You can tell dicepwgen to use another dictionary file with
the option B<-f>.
If you're using a precomputed diceware list, use the parameter
B<-n>, in which case dicepwgen will use all entries in the file.
The program only uses words which contain 7bit ASCII letters
(a-zA-Z0-9), which are easier for password usage anyway.
=head1 FILES
B</usr/share/dict/american-english>: default dictionary file.
You can use almost any dictionary file you want. Dicepwgen expects
the file to be in the following format: one word per line.
You can also use precomputed diceware word lists by adding the
option B<-n> to the commandline. If the file already contains
numbers, you have to remove them before using. Say, the file
looks like this:
11126 abase
11131 abash
11132 abate
11133 abbas
Prepare the file with this shell oneliner:
grep "^[0-9]" dicewarelist.txt | awk '{print $2}' >> newlist.txt

Current known issues:
=over
=item *
The program does not count the lines in a dictionary file before
using it. If the file contains a low number of entries (e.g. because
it is a precomputed diceware word list and B<-n> has not been
specified), it seems to "hang". In fact it runs very long because it
jumps over a random number of entries and restarts from the beginning
again and again til the required number of words has been collected (7776).
