+	Parameters for |:mkspell|.  This tunes when to start compressing the
+	word tree.  Compression can be slow when there are many words, but
+	it's needed to avoid running out of memory.  The amount of memory used
+	per word depends very much on how similar the words are, that's why
+	this tuning is complicated.
+
+	There are three numbers, separated by commas:
+		{start},{inc},{added}
+
+	For most languages the uncompressed word tree fits in memory.  {start}
+	gives the amount of memory in Kbyte that can be used before any
+	compression is done.  It should be a bit smaller than the amount of
+	memory that is available to Vim.
+
+	When going over the {start} limit the {inc} number specifies the
+	amount of memory in Kbyte that can be allocated before another
+	compression is done.  A low number means compression is done after
+	less words are added, which is slow.  A high number means more memory
+	will be allocated.
+
+	After doing compression, {added} times 1024 words can be added before
+	the {inc} limit is ignored and compression is done when any extra
+	amount of memory is needed.  A low number means there is a smaller
+	chance of hitting the {inc} limit, less memory is used but it's
+	slower.
+
+	The languages for which these numbers are important are Italian and
+	Hungarian.  The default works for when you have about 512 Mbyte.  If
+	you have 1 Gbyte you could use: >
+		:set mkspellmem=900000,3000,800
+<	If you have less than 512 Mbyte |:mkspell| may fail for some
+	languages, no matter what you set 'mkspellmem' to.
