file data, I used imaginary abstract class StreamReader to do all
the input (check streams.php). For your convenience, I've already
provided two classes for reading files: FileReader and
StringReader (CachedFileReader is a combination of the two: it
loads entire file contents into a string, and then works on that).
See example below for usage. You can for instance use StringReader
when you read in data from a database, or you can create your own
derivative of StreamReader for anything you like.

Bugs
Plural-forms field in MO header (translation for empty string,
i.e. "") is treated according to PHP syntactic rules (it's
eval()ed). Since these should actually follow C syntax, there are
some problems.
For instance, I'm used to using this:
Plural-Forms: nplurals=3; plural=n%10==1 && n%100!=11 ? 0 : \
n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2;
but it fails with PHP (it sets $plural=2 instead of 0 for $n==1).
The fix is usually simple, but I'm lazy to go into the details of
PHP operator precedence, and maybe try to fix it. In here, I had
to put everything after the first ':' in parenthesis:
Plural-Forms: nplurals=3; plural=n%10==1 && n%100!=11 ? 0 : \
(n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);
That works, and I'm satisfied.
Besides this one, there are probably a bunch of other bugs, since
I hate PHP (did I mention it already? no? strange), and don't
know it very well. So, feel free to fix any of those and report
them back to me at <danilo@kvota.net>.

Interesting TODO:
TODO:
o Try to parse "plural-forms" header field, and to follow C syntax
rules. This won't be easy.
o Improve speed to be even more comparable to the native gettext
implementation.
Boring TODO:
o Learn PHP and fix bugs, slowness and other stuff resulting from
my lack of knowledge (but *maybe*, it's not my knowledge that is
bad, but PHP itself ;-).
