+npm-version(3) -- Bump a package version
+========================================
+
+## SYNOPSIS
+
+    npm.commands.version(newversion, callback)
+
+## DESCRIPTION
+
+Run this in a package directory to bump the version and write the new
+data back to the package.json file.
+
+If run in a git repo, it will also create a version commit and tag, and
+fail if the repo is not clean.
+
+Like all other commands, this function takes a string array as its first
+parameter. The difference, however, is this function will fail if it does
+not have exactly one element. The only element should be a version number.
