bad value for range (ArgumentError): Exception raised when trying to use tomdoc in command line

[Bodacious]

Hey - TomDoc looks great! When I tried it out today I kept hitting this exception though

/Users/Gavin/.rvm/gems/ruby-1.9.3-p0-perf/gems/tomdoc-0.2.4/lib/tomdoc/tomdoc.rb:124:in `block in tomdoc': bad value for range (ArgumentError)

I get this when I simply call

$ tomdoc some_ruby_file.rb

I've created a repo with the code I was trying to document: https://github.com/bodacious/TomDocTest

I'm using Ruby 1.9.3

The full stack trace is

Thanks for reporting. Looks like the problem is when it trys to parse documentation with only one line of text. I have just pushed a new version (0.2.5). Let me know if that fixes it for you.

[Bodacious]

It does indeed - thanks a lot
