+If you wish to affect only a single repository (i.e., to assign
+attributes to files that are particular to one user's workflow), then
+attributes should be placed in the `$GIT_DIR/info/attributes` file.
+Attributes which should be version-controlled and distributed to other
+repositories (i.e., attributes of interest to all users) should go into
+`.gitattributes` files.

Sometimes you would need to override an setting of an attribute
for a path to `unspecified` state. This can be done by listing
the name of the attribute prefixed with an exclamation point `!`.
These attributes affect how the contents stored in the
repository are copied to the working tree files when commands
-such as `git checkout` and `git merge` run. They also affect how

+If `core.safecrlf` is set to "true" or "warn", git verifies if

+conversions; for "warn", git only prints a warning but accepts

Generating diff text

with the above configuration, i.e. `j-c-diff`, with 7
parameters, just like `GIT_EXTERNAL_DIFF` program is called.

Defining a custom hunk-header

begins with an alphabet, an underscore or a dollar sign is used,

use customized pattern to make a selection.
There are a few built-in patterns to make this easier, and `tex`

+Creating an archive
+~~~~~~~~~~~~~~~~~~~
+
+`export-ignore`
+^^^^^^^^^^^^^^^
+
+Files and directories with the attribute `export-ignore` won't be added to
+archive files.
+
+`export-subst`
+^^^^^^^^^^^^^^
+
+If the attribute `export-subst` is set for a file then git will expand
+several placeholders when adding this file to an archive. The
+expansion depends on the availability of a commit ID, i.e., if
+linkgit:git-archive[1] has been given a tree instead of a commit or a
+tag then no replacement will be done. The placeholders are the same
+as those for the option `--pretty=format:` of linkgit:git-log[1],
+except that they need to be wrapped like this: `$Format:PLACEHOLDERS$`
+in the file. E.g. the string `$Format:%H$` will be replaced by the
+commit hash.
