Yes, It's intended.  Mostly because security reason.  If you want to
load your own file, I think you should express it explicitly.

But you can use RUBYOPT environment variable for your purpose.

  export RUBYOPT
  RUBYOPT='I."
  ruby -e 'p $LOAD_PATH'
  [".", "/usr/lib/ruby/site_ruby/1.5/i586-linux", "/usr/lib/ruby/site_ruby/1.5", "/usr/lib/ruby/site_ruby", "/usr/lib/ruby/1.5/i586-linux", "/usr/lib/ruby/1.5", "."]

|Other opinions?

I think relative path is too dangerous.  BTW, the sequence in the
Perl's load path is reversed somehow.

|And while thinking about this, I have another proposal. How about to
|include the directory from where the program was started into the load
|path too? That would enable me to put my application with its support
|libs into an own subdirectory and after starting, the load path would
|already contain this directory too! So its support libs could easily
|be required too. But this should only happen, of course, if $0 is not
|'-' or '-e'.

I can understand you.  But `$0' path is not portable.
