//  - *const instructions may use a constant larger than the instruction can encode.
//    In this case the assembler expands to multiple instructions and uses tmp
//    register (R11).

// Suffixes encode the bit width of various instructions.
// W (word)      = 32 bit
// H (half word) = 16 bit
// HU            = 16 bit unsigned
// B (byte)      = 8 bit
// BU            = 8 bit unsigned

The advantage of using this pattern when working only with pom metadata is that both variants are discoverable through the version.
The disadvantage is that there is no information what the different version suffixes mean semantically.
So in the case of conflict, Gradle would just pick the highest version when comparing the version strings.
