+# owl(1)
+
+*The moon is bright. The owls are ready for the hunt.*
+
+Owl is a file renaming tool; it removes character from file names which are 
+not compatible with `FAT` file systems (typically `FAT32` or `exFAT`).
+
+```
+owl COMMAND OPTIONS FILE1 FILE2 ...
+```
+
+
+## CLEAN COMMAND
+Rename `FILE`s given at the command line such that all `FAT`-incompatible 
+characters are removed. By default it replaces invalid characters with 
+`_U{Unicode Code Point}_`, but this can be changed, see the `--strategy` 
+flag below.
+
+## Options:
+
+### -s, --strategy STRATEGY
+Change what happens to invalid characters. Choices are:
+
+- "remove": just remove the characters. If left with an empty string, rename 
+  to "\_empty_".
+- "code-point": replace each character with "\_Unum_", where "num" is the 
+  Unicode Code Point of the character.
+
+## HELP COMMAND
+Show a small help message.
+
+## VERSION COMMAND
+Show version information.
+
+
+## GENERAL OPTIONS
+### -n, --dry-run
+Causes Owl to just print a representation of what would be done without 
+actually renaming any files.
+
+### -v, --version
+Causes the `version` command to be run, regardless of what other arguments 
+are given.
+
+### -h, --help
+Causes the `help` command to be run, regardless of what other arguments are 
+given.
