What's the best library for manipulating JPEG metadata?

I'm after a library that can read and write JPEG image metadata. For example if I wanted to embed and read back a short description or story relating to the jpeg image, in the image file itself, what development library/s would you recommend?

I'm not too fussed about what language (it's a new project), though I've tagged this question for languages I'm familiar with (I'd also consider other languages however). Preferably something that's relatively cross-platform (mac/linux/win), such as Java, FreePascal/Lazarus, C++, Objective-C, etc (to be honest I'm not that familiar with cross-platform, so no idea whether C# is a possibility) - aside from more popular ones such as Java or .NET, it would be preferable for there be no requirement to have any particular framework installed.

Looks easy to use

Exif does it all but it is written in Perl.

Perl is cross-platform.

Yes, but don't you need to install a framework of some sort, at least in Windows? I don't know much about perl, but would be good to learn a new language. Just want to produce something that won't be too much of a hassle to install...

Well you need to install Perl :) In terms of what Perl module (library) you actually use to do the image manipulation, that's where your cross-platform question needs to be asked. It depends on whether the Perl module you use is pure Perl or depends on a non-Perl library to do the actual work.

A: 

libjpeg is an excellent library written in C. It can be used to do just about any type of jpeg manipulation. I have successfully compiled it in windows, unix and linux.
