Welcome to Prawn, the best pure-Ruby PDF solution ever!
This is version 0.8
For those coming from Prawn 0.7 or earlier, note that this release has
some API breaking changes as well as many new features. *** You'll want
to know about these changes, as we will no longer be supporting
Prawn 0.7 or any earlier version of Prawn***
For details on what has changed, see:
http://wiki.github.com/sandal/prawn/changelog
If you have questions, contact us at:
http://groups.google.com/group/prawn-ruby
To submit a patch or report a bug, select the appropriate package below:
http://github.com/sandal/prawn
http://github.com/sandal/prawn-layout
http://github.com/madriska/prawn-security
Prawn is meant for experienced Ruby hackers, so if you are new to Ruby, you
might want to wait until you've had some practice with the language before
expecting Prawn to work for you. Things may change after 1.0, but for now
if you're not ready to read source code and patch bugs or missing features
yourself (with our help), Prawn might not be the right fit.
But if you know what you're getting yourself into, enjoy!
