Contains reports whether x contains s.

FoldDup reports a pair of strings from the list that are equal according to strings.EqualFold.

HasFilePathPrefix reports whether the filesystem path s begins with the elements in prefix.

HasPathPrefix reports whether the slash-separated path s begins with the elements in prefix.

StringList flattens its arguments into a single []string.

ToFold returns a string with the property that strings.EqualFold(s, t) iff ToFold(s) == ToFold(t) This lets us test a large set of strings for fold-equivalent duplicates without making a quadratic number of calls to EqualFold.

TrimFilePathPrefix returns s without the leading path elements in prefix.

Uniq removes consecutive duplicate strings from ss.
