I've tried to replicate and extend the first results I got, but I don't seem to be calling this properly. The logic for Getopt::Long seems pretty opaque to me now. Do you see why this is fundamentally different than what worked before?

$ ./2.analyse_text.pl --input-corpus 84-0.txt  --ngram-length 4 --outp
+ut-state 4.shelley.state
args are --input-corpus 84-0.txt --ngram-length 4 --output-state 4.she
+lley.state
Unknown option: input-corpus
Unknown option: ngram-length
Unknown option: output-state
Usage : ./2.analyse_text.pl <options>


Something wrong with command-line parameters...
$ cat 2.analyse_text.pl 
#!/usr/bin/env perl
