+SPELL FILE MISSING		*spell-SpellFileMissing* *spellfile.vim*
+
+If the spell file for the language you are using is not available, you will
+get an error message.  But if the "spellfile.vim" plugin is active it will
+offer you to download the spell file.  Just follow the instructions, it will
+ask you where to write the file.
+
+The plugin has a default place where to look for spell files, on the Vim ftp
+server.  If you want to use another location or another protocol, set the
+g:spellfile_URL variable to the directory that holds the spell files.  The
+|netrw| plugin is used for getting the file, look there for the speficic
+syntax of the URL.  Example: >
+	let g:spellfile_URL = 'http://ftp.vim.org/vim/runtime/spell'
+You may need to escape special characters.
+
+The plugin will only ask about downloading a language once.  If you want to
+try again anyway restart Vim, or set g:spellfile_URL to another value (e.g.,
+prepend a space).
+
+To avoid using the "spellfile.vim" plugin do this in your vimrc file: >
+
+	let loaded_spellfile_plugin = 1
+
+Instead of using the plugin you can define a |SpellFileMissing| autocommand to
+handle the missing file yourself.  You can use it like this: >
+
+	:au SpellFileMissing * call Download_spell_file(expand('<amatch>'))
+
+Thus the <amatch> item contains the name of the language.  Another important
+value is 'encoding', since every encoding has its own spell file.  With two
+exceptions:
+- For ISO-8859-15 (latin9) the name "latin1" is used (the encodings only
+  differ in characters not used in dictionary words).
+- The name "ascii" may also be used for some languages where the words use
+  only ASCII letters for most of the words.
+
+The default "spellfile.vim" plugin uses this autocommand, if you define your
+autocommand afterwars you may want to use ":au! SpellFileMissing" to overrule
+it.  If you define your autocommand before the plugin is loaded it will notice
+this and not do anything.
