[PATCH 1/6] user-manual: edit "ignoring files" for conciseness

["J. Bruce Fields" <bfields@citi.umich.edu>]

From: J. Bruce Fields <bfields@puzzle.fieldses.org>

The immediate motivation for writing this section was to explain the
various places ignore patterns could be used.  However, I still think
.gitignore is the case most people will want to learn about first.  It
also makes it a bit more concrete to introduce ignore patterns in the
context of .gitignore first.  And the existance of gitignore(5) relieves
the pressure to explain it all here.

So, stick to the .gitignore example, with only a brief mention of the
others, explain the syntax only by example, and leave the rest to
gitignore(5).

-Git therefore provides "exclude patterns" for telling git which files to

-gitlink:gitignore[5] manual page, but the heart of the concept is simply
-a list of files which git should ignore. Entries in the list may contain
-globs to specify multiple files, or may be prefixed by "`!`" to
-explicitly include (un-ignore) a previously excluded (ignored) file
-(i.e. later exclude patterns override earlier ones).  The following

+You can tell git to ignore certain files by creating a file called .gitignore
+in the top level of your working directory, with contents such as:

 # Lines starting with '#' are considered comments.

-The next question is where to put these exclude patterns so that git can
-find them. Git looks for exclude patterns in the following files:
-
-`.gitignore` files in your working tree:::
-	   You may store multiple `.gitignore` files at various locations in your
-	   working tree. Each `.gitignore` file is applied to the directory where
-	   it's located, including its subdirectories. Furthermore, the
-	   `.gitignore` files can be tracked like any other files in your working
-	   tree; just do a "`git add .gitignore`" and commit. `.gitignore` is
-	   therefore the right place to put exclude patterns that are meant to
-	   be shared between all project participants, such as build output files
-	   (e.g. `\*.o`), etc.
-`.git/info/exclude` in your repo:::
-	   Exclude patterns in this file are applied to the working tree as a
-	   whole. Since the file is not located in your working tree, it does
-	   not follow push/pull/clone like `.gitignore` can do. This is therefore
-	   the place to put exclude patterns that are local to your copy of the
-	   repo (i.e. 'not' shared between project participants), such as
-	   temporary backup files made by your editor (e.g. `\*~`), etc.
-The file specified by the `core.excludesfile` config directive:::
-	   By setting the `core.excludesfile` config directive you can tell git
-	   where to find more exclude patterns (see gitlink:git-config[1] for
-	   more information on configuration options). This config directive
-	   can be set in the per-repo `.git/config` file, in which case the
-	   exclude patterns will apply to that repo only. Alternatively, you
-	   can set the directive in the global `~/.gitconfig` file to apply
-	   the exclude pattern to all your git repos. As with the above
-	   `.git/info/exclude` (and, indeed, with git config directives in
-	   general), this directive does not follow push/pull/clone, but remain
-	   local to your repo(s).
-
-[NOTE]
-In addition to the above alternatives, there are git commands that can take
-exclude patterns directly on the command line. See gitlink:git-ls-files[1]
-for an example of this.
+See gitlink:gitignore[5] for a detailed explanation of the syntax.  You can
+also place .gitignore files in other directories in your working tree, and they
+will apply to those directories and their subdirectories.  The `.gitignore`
+files can be added to your repository like any other files (just run `git add
+.gitignore` and `git commit`, as usual), which is convenient when the exclude
+patterns (such as patterns matching build output files) would also make sense
+for other users who clone your repository.
+
+If you wish the exclude patterns to affect only certain repositories
+(instead of every repository for a given project), you may instead put
+them in a file in your repository named .git/info/exclude, or in any file
+specified by the `core.excludesfile` configuration variable.  Some git
+commands can also take exclude patterns directly on the command line.
+See gitlink:gitignore[5] for the details.
