++`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.
