This one is trivial.
For testing my timezone code, I often need to recurse through all the directories where the Zoneinfo binary files are. I got tired of rewriting the programs depending on whether I was testing on Linux or Windows, so I decided to write a little framework that would be portable to both operating systems. It doesn’t solve all the problems (the two systems provide different information about directory entries), but at least I don’t have to completely restructure the main loops. 😎
There are no new ideas here: how to loop through directories is really old news; and since it’s not particularly original on my part, all the code is in the public domain.
