-Sets the mask of events to watch for. Refer to the
-.B MASKS
-section of this manual page for more details. you can specify multiple masks by
-providing multiple

-.SH MASKS
-A mask is a number that

-uses to find out what events it should check for. When using
-.BI \-m\ mask\fR,

+.Sh MASKS
+The mask is a numeric value passed to inotify to specify the events that should
+be raised. Multiple events can be registered by summing them up, and passing
+the result to the
+.Fl m
+flag. The mask can take any of the values below, or a sum of them:
-.SH EXAMPLES
-
-.SS Watching single events
-This command will watch
-.B IN_CREATE
-events in the given directory, and play a sounds whenever a file is created in
-this directory. This can be useful to get notified of new incoming emails
-(fetched locally)
-.nf
-wendy -m 256 -f ~/mail/INBOX/new -e play /usr/share/sound/bell.wav
-.fi
-
-.SS Watching for multiple events
-To watch multiple events, you just need to sum them up before giving the mask to
-.B wendy
-\. For example, here is how you'd watch both
-.B IN_MOVED_FROM (64)
-and
-.B IN_MOVED_TO (128)
-events on a directory: 128 + 64 = 192
-.nf
-wendy -m 192 -f ~/var/directory -v
-.fi
-
-.SS Watching multiple files
-.B wendy
-gives you two different ways to watch multiple files. Either by providing
-multiple
-.B \-f
-flags, or by feeding it from stdin. Let's say you have the following structure:
-.nf
- .
- |-- Makefile
- |-- library.c
- |-- library.h
- `-- program.c
-.fi
-If you want to automatically run
-.B make
-whenever a C source file is modified, you can use the following commands
-.nf
-wendy -m 8 -f library.c -f program.c -e make
-.fi
-OR
-.nf
-find -name '*.c' | wendy -m 8 -e make
-.fi
-
-.SS Using different masks on different files
-The order of the flags provided matters. So if you want to watch mutliple
-events, you can simply tidy the arguments to do what you want.
-This example will raise both
-.B IN_CREATE
-events in the given directory, and
-.B IN_ACCESS
-events on existing files
-.nf
-wendy -v -m 256 -f /var/log -m 1 -f /var/log/message -f /var/log/auth

+.Ed
+.Ss Watch multiple events
+You can watch multiple events by passing the sum of their numerical value to
+the
+.Fl m
+flag. This command will watch both IN_CREATE (256) and IN_DELETE (512) in the
+current directory, and report these events to stdout (same effect as using the
+.Fl v
+flag)
