How to remove duplicate pages from a PDF?

I have a pdf of an ebook 开发者_StackOverflow中文版which has many pages duplicated, and I would like to remove them.

There are many PDF toolkits that could do this. You don't say which language or framework, so it's hard to recommend one.

You could also use Adobe Acrobat if you don't want to do it programmatically.
