4: What do these mean: etc/SERVICE, src/config.h, lisp/default.el? These are files that come with Emacs. The Emacs distribution is divided into subdirectories; the important ones are "etc", "lisp", and "src". If you use Emacs, but don't know where it is kept on your system, start Emacs, then type "C-h v data-directory RET". The directory name displayed by this will be the full pathname of the installed "etc" directory. The location of your Info directory (i.e., where on-line documentation is stored) is kept in the variable Info-default-directory-list. Use "C-h v Info-default-directory-list RET" to see the contents of this variable, which will be a list of directory names. The last directory in that list is probably where most Info files are stored. By default, Info documentation is placed in /usr/local/info. Some of these files are available individually via FTP or e-mail; see question 20. All are available in the source distribution. WARNING: Your system administrator may have removed the src directory and many files from the etc directory.
