I used AI to help me learn Keyman, and resulted in making this:

c My Fantasy Script Keyboard
store(&VERSION) '1.0'
store(&NAME) 'My Fantasy Script'
store(&BITMAP) 'fntsy.ico'
store(&LAYOUTFILE) 'fntsy.kmn'
store(&TARGETS) 'windows macosx linux web'

begin Unicode > use(main)

group(main) using keys
+ '0' > U+00A1 c Mapping for the '0' key
+ '1' > U+00A6 c Mapping for the '1' key
+ '2' > U+00A2 c Mapping for the '2' key
+ '3' > U+00A3 c Mapping for the '3' key
+ '4' > U+00A5 c Mapping for the '4' key
+ '5' > U+00A4 c Mapping for the '5' key
+ '6' > U+00A9 c Mapping for the '6' key
+ '7' > U+00A7 c Mapping for the '7' key
+ '8' > U+00AB c Mapping for the '8' key
+ '9' > U+00AE c Mapping for the '9' key

What am I doing wrong?

Why do I get this output when running this command?

$ kmc build --color --debug tone.kmn
fntsy.kmn - info KM05002: Building fntsy.kmn
fntsy.kmn:2 - warn KM02081: The keyboard file is an old version
fntsy.kmn:2 - error KM0200D: Invalid 'version' command
fntsy.kmn - info KM05007: fntsy.kmn failed to build.

How do I fix this? There documentation is quite hard to follow and find solutions to, so I’m probably using the wrong version of the file format (though I couldn’t find the right one or what’s wrong with mine), and the invalid version is throwing me off too.
