+Checking whitespace errors
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`whitespace`
+^^^^^^^^^^^^
+
+The `core.whitespace` configuration variable allows you to define what
+`diff` and `apply` should consider whitespace errors for all paths in
+the project (See gitlink:git-config[1]). This attribute gives you finer
+control per path.
+
+Set::
+
+ Notice all types of potential whitespace errors known to git.
+
+Unset::
+
+ Do not notice anything as error.
+
+Unspecified::
+
+ Use the value of `core.whitespace` configuration variable to
+ decide what to notice as error.
+
+String::
+
+ Specify a comma separate list of common whitespace problems to
+ notice in the same format as `core.whitespace` configuration
+ variable.

EXAMPLE

+Creating an archive
+~~~~~~~~~~~~~~~~~~~
+
+`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
+gitlink: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 gitlink: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.
