+NAME
+----
+git-stripspace - Remove unnecessary whitespace
+
+
+SYNOPSIS
+--------
+[verse]
+'git stripspace' [-s | --strip-comments]
+'git stripspace' [-c | --comment-lines]
+
+DESCRIPTION
+-----------
+
+Read text, such as commit messages, notes, tags and branch
+descriptions, from the standard input and clean it in the manner
+used by Git.
+
+With no arguments, this will:
+
+- remove trailing whitespace from all lines
+- collapse multiple consecutive empty lines into one empty line
+- remove empty lines from the beginning and end of the input
+- add a missing '\n' to the last line if necessary.
+
+In the case where the input consists entirely of whitespace characters, no
+output will be produced.
+
+*NOTE*: This is intended for cleaning metadata. Prefer the `--whitespace=fix`
+mode of linkgit:git-apply[1] for correcting whitespace of patches or files in
+the repository.
+
+OPTIONS
+-------
+-s::
+--strip-comments::
+	Skip and remove all lines starting with a comment character (default '#').
+
+-c::
+--comment-lines::
+	Prepend the comment character and a blank space to each line. Lines will automatically
+	be terminated with a newline. On empty lines, only the comment character
+	will be prepended.
+
+EXAMPLES
+--------
+
+Given the following noisy input with '$' indicating the end of a line:
+
+---------
+|A brief introduction   $
+|   $
+|$
+|A new paragraph$
+|# with a commented-out line    $
+|explaining lots of stuff.$
+|$
+|# An old paragraph, also commented-out. $
+|      $
+|The end.$
+|  $
