LessStrings returns whether s is less than t lexicographically.
Strings returns an integer comparing two strings lexicographically.
Comparer can be used to compare two values. This will be used when using the le, ge etc. operators in the templates. Compare returns -1 if the given version is less than, 0 if equal and 1 if greater than the running version.
Eqer can be used to determine if this value is equal to the other. The semantics of equals is that the two value are interchangeable in the Hugo templates.
ProbablyEqer is an equal check that may return false positives, but never a false negative.
