Why do I have a `~/texmf` directory?

Question

Shortly after setting up emacs with auctex I noticed that a directory ~/texmf on my system. Issuing $ tree ~/texmf returns

~/texmf
|- web2c
   |- tlmgr.log

I'm having trouble understanding why this directory exists and what the file tlmgr.log does. In particular, I'm curious what the effects of deleting the directory would be.

See https://tex.stackexchange.com/questions/66614/change-texmfhome-per-user

This tells you how to change the location (and name) of the directory. It also gives an explanation of the reason it exists.
