HOWTO needed: how to add my own module to making list?

[Oleg Strikov]

Good day!
Ive created my own grub file validation module, but I can only make it by renaming to standart "hello module" :(

What ive done:
1) add my module source into ./commands folder
2) add validate.mod
 to pkgdata_MODULES (common.rmk)
3) add some template data
    # For validate.mod.
    validate_mod_SOURCES = commands/validate.c
    validate_mod_CFLAGS = $(COMMON_CFLAGS)
    validate_mod_LDFLAGS = $(COMMON_LDFLAGS)
to the same file

What point ive forgotten?

Thanks!
