Are there any LaTeX packages that can assist with reading and writing to files? I am trying to develop a solution to the following problem:
1) I am producing a long report regularly. Part of the report include items like
Key date: 12 Sep 2010 Complete Floor 1
Key date: 18 Sep 2010 Other activity
2) It will be nice to have all these dates saved into a sort of an aux file and then import later as a section of its own. It will also need to be sorted.
I have so far looked at the answers package for inspiration and also thought of hacking the index mechanism. Any ideas and pointers would be greatly appreciated.
