Find/replace underscored words to camelCase words using regex?

Question

I have a ton of text files that are tagged with underscore-connected words like @some_text, but I would like to convert those to tags in camel case, like @someText. How can I use regex (either in vim or with sed or similar tool) to find and replace these?

If you're using GNU sed, you could do s=_\([A-Za-z]\)=\u\1=g.
