Ah, I should say so...  Thank you.

% ruby -d myscript.rb

But bear in mind that some standard or RAA libraries are not '-d' aware...
They do not break processing your program but might show debug print
which is embedded by the its author.  Try it.

% grep \$DEBUG $RUBY_LIB

Agree.

I think that redistributable libraries (applications, too?) should
have its self-testing code.  Using a standardized testing method
like RubyUnit (by Suketa-san) or testsupp (by \cle) rather than using
'if $DEBUG' much helps automatic self-testing because those testing
method not only invokes methods but also checks those results.


1. Embedding syntax...

  =begin test RubyUnit (other additional information like its version)
  =end

  =begin test testsupp
  =end

How about it?


2. Self-testing execution...

Could it be acceptable?  Matz?
