\fIDEST_WIMFILE\fR does not yet exist, since if \fIDEST_WIMFILE\fR exists, the
compression type must be the same as that of \fIDEST_WIMFILE\fR.
-\fITYPE\fR may be "none", "maximum", or "fast". By default, it is "fast".
+\fITYPE\fR may be "none", "maximum", or "fast". By default, it is the same as
+that of the input WIM file.
You may also specify the actual names of the compression algorithms, "XPRESS"
and "LZX", instead of "fast" and "maximum", respectively.
