+==============================================================================================
+
+## SYNOPSIS
+
+`git media smudge` <path>
+
+## DESCRIPTION
+
+Smudge takes a Git Media pointer file in STDIN, parses out the pointer's ID,
+and then dumps the file's contents to STDOUT.  The file will be downloaded from
+the Git Media endpoint if needed. The optional <path> argument is only used for
+a progress bar.
+
+Smudge is typically run by Git's smudge filter, configured by the repository's
+Git attributes.
