+File Handling
+*************
+
+ The basic unit of stored data in Unix is the "file". To edit a file,
+you must tell Emacs to examine the file and prepare a buffer containing
+a copy of the file's text. This is called "visiting" the file. Editing
+commands apply directly to text in the buffer; that is, to the copy
+inside Emacs. Your changes appear in the file itself only when you
+"save" the buffer back into the file.
+
+ In addition to visiting and saving files, Emacs can delete, copy,
+rename, and append to files, and operate on file directories.
+
+* Menu:
+
+* File Names:: How to type and edit file name arguments.
+* Visiting:: Visiting a file prepares Emacs to edit the file.
+* Saving:: Saving makes your changes permanent.
+* Reverting:: Reverting cancels all the changes not saved.
+* Auto Save:: Auto Save periodically protects against loss of data.
+* Version Control:: Version control systems (RCS and SCCS).
+* ListDir:: Listing the contents of a file directory.
+* Comparing Files:: Finding where two files differ.

-Change Logs and VC
-------------------
-
- If you use RCS for a program and also maintain a change log file for
-it (*note Change Log::), you can generate change log entries
-automatically from the version control log entries:
-
-`C-x v a'
- Visit the current directory's change log file and create new
- entries for versions checked in since the most recent entry in the
- change log file (`vc-update-change-log').
-
- This command works with RCS only; it does not work with SCCS.
-
- For example, suppose the first line of `ChangeLog' is dated 10 April
-1992, and that the only check-in since then was by Nathaniel Bowditch
-to `rcs2log' on 8 May 1992 with log text `Ignore log messages that
-start with `#'.'. Then `C-x v a' visits `ChangeLog' and inserts text
-like this:
-
- Fri May 8 21:45:00 1992 Nathaniel Bowditch (nat@apn.org)
-
- * rcs2log: Ignore log messages that start with `#'.
-
-You can then edit the new change log entry further as you wish.
-
- Normally, the log entry for file `foo' is displayed as `* foo: TEXT
-OF LOG ENTRY'. The `:' after `foo' is omitted if the text of the log
-entry starts with `(FUNCTIONNAME): '. For example, if the log entry
-for `vc.el' is `(vc-do-command): Check call-process status.', then the
-text in `ChangeLog' looks like this:
-
- Wed May 6 10:53:00 1992 Nathaniel Bowditch (nat@apn.org)
-
- * vc.el (vc-do-command): Check call-process status.
-
- When `C-x v a' adds several change log entries at once, it groups
-related log entries together if they all are checked in by the same
-author at nearly the same time. If the log entries for several such
-files all have the same text, it coalesces them into a single entry.
-For example, suppose the most recent checkins have the following log
-entries:
-
-For `vc.texinfo':
- Fix expansion typos.
-For `vc.el':
- Don't call expand-file-name.
-For `vc-hooks.el':
- Don't call expand-file-name.
-
- They appear like this in `ChangeLog':
-
- Wed Apr 1 08:57:59 1992 Nathaniel Bowditch (nat@apn.org)
-
- * vc.texinfo: Fix expansion typos.
-
- * vc.el, vc-hooks.el: Don't call expand-file-name.
-
- Normally, `C-x v a' separates log entries by a blank line, but you
-can mark several related log entries to be clumped together (without an
-intervening blank line) by starting the text of each related log entry
-with a label of the form `{CLUMPNAME} '. The label itself is not
-copied to `ChangeLog'. For example, suppose the log entries are:
-
-For `vc.texinfo':
- {expand} Fix expansion typos.
-For `vc.el':
- {expand} Don't call expand-file-name.
-For `vc-hooks.el':
- {expand} Don't call expand-file-name.
-
-Then the text in `ChangeLog' looks like this:
-
- Wed Apr 1 08:57:59 1992 Nathaniel Bowditch (nat@apn.org)
-
- * vc.texinfo: Fix expansion typos.
- * vc.el, vc-hooks.el: Don't call expand-file-name.
-
- A log entry whose text begins with `#' is not copied to `ChangeLog'.
-For example, if you merely fix some misspellings in comments, you can
-log the change with an entry beginning with `#' to avoid putting such
-trivia into `ChangeLog'.
