+
+Pass the following arguments:
+
+	* \`<repo>\`: ":user/:name" of the repository. For example, "foca/mpp".
+	* \`<tag>\`: Name of the tag for this release. For example, "v1.0.0".
+	* \`<release name>\`: Optional suffix for the release name.
+
+You can pass a list of files to upload as release assets by giving them after a
+\`--\` argument.
+
+If you supply text on \`STDIN\` it will be used as the release notes.
+
+EXAMPLES:
+
+	$ $0 foca/mpp v1.0.0 -- pkg/*.tar.gz
+
+	Creates a release named "mpp v1.0.0" and adds any tar.gz file in
+	\`./pkg\` as an asset.
+
+	$ $0 foca/mpp v1.0.1 "Bugfixes" -- pkg/*.tar.gz < notes.md
+
+	Creates a release named "mpp v1.0.1: Bugfixes", adds any tar.gz
+	file in \`./pkg\` as an asset, and uses the contents of \`notes.md\`
+	as the release notes.
+
+NOTE:
+
+This uses your \`.netrc\` file to authenticate with GitHub. In order to run the
+script, make sure you have **both** \`api.github.com\` and \`upload.github.com\` in
+this file. For example:
+
+machine api.github.com
+  login foca
+  password <an access token>
+machine uploads.github.com
+  login foca
+  password <an access token>
+
+Generate this access token at https://github.com/settings/tokens and make sure
+it has access to the \`"repo"\` scope.
