Ive worked on a project now for quite some time now. It has evolved to a lot of files and directories which is quite a mess, it may seem like. So I was considering re factoring parts of the code but as I do not know how or where to start I need to build a diagram of the dependencies to get a better overview. So my question is really; Is there a tool or script out there that can take Perl files and build up a list of which modules "requires" other modules or "uses" other packages ?
