making TeX documents ragged left justified?

How can I make my entire LaTeX document (using TeXShop in Mac OS开发者_JAVA技巧 X) left justified, in a "ragged left" mode? I don't want to use blocks of \begin{flushleft} everywhere, I just want to declare somewhere in the document header that the whole document should be this way. Right now everything is fully justified (like newspapers) by default.

This should do it globally:

\raggedright

See the ragged2e package to enable hyphenation in ragged prargraphs.

Did you try:

\raggedleft
