Our scheme for naming directories and files is an attempt to be sensible for Unix, DOS or Windows. In Unix, unlike in DOS or Windows, directory and file names are case sensitive.
Some subdirectory names begin with a period.
These directories contain control information rather than data files. Files which begin with a capital letter are special files which contain important information. Naming them with an initial capital letter causes them to appear first in Unix directory listings. Some directories contain a Readme.txt file. This file will explain the purpose of the directory and some of the files it contains.
