This manual page documents briefly the 
\fBuml_moo\fR command.

This manual page was written for the \fBDebian GNU/Linux\fP distribution 
because the original program does not have a manual page. 
Instead, it has documentation in HTML format; see below.

\fBuml_moo\fR is a program to merge a COW 
(copy-on-write) file with its backing file, and write the result 
to a new backing file.  This can be used periodically to update 
the backing file with the changes made in the COW file. 
.PP 
NOTE: you can save a lot of disk space using COW files. 
When checking the size of the COW file in order to see the gobs 
of space that you're saving, make sure you use 'ls \-ls' to see the actual 
disk consumption rather than the length of the file. The COW file is 
sparse, so the length will be very different from the disk usage.
