Better error reporting on the command line

[szabgab]

By mistake I ran dancer -a Name in a read-only directory. It gave me the options, but it did not tell me why did it fail. Spending 10 frustrated minutes on this was not fun.

Could there be more specific error messages explaining why did the command fail?

There is a -message flag for pod2usage(). I think that could be used for this.

(encountered in Dancer 1.311)

Might be related to GH #706

seems already fixed, see GH #897. Close this issue?

@mokko thanks again! I owe a beverage for all the triage you've done! :)
