+  Gets the new contents file from
+    https://raw.githubusercontent.com/vim/vim/master/runtime/CONTENTS
+  Goes over each line, compares the checksum and gets the file if it differs.
+- Include a minimal required Vim version?
+- For an installation, use "sudo" after getting all the files, only copy them.
+   need a temp directory tree.
+- For Windows generate a .bat file with "runas" (see StackOverflow).
+- Include a wget.exe or curl.exe in the distribution?
