-// Pos is a compact encoding of a source position within a file set.
-// It can be converted into a Position for a more convenient, but much
-// larger, representation.
-//
-// The Pos value for a given file is a number in the range [base, base+size],
-// where base and size are specified when a file is added to the file set.
-// The difference between a Pos value and the corresponding file base
-// corresponds to the byte offset of that position (represented by the Pos value)
-// from the beginning of the file. Thus, the file base offset is the Pos value
-// representing the first byte in the file.
-//
-// To create the Pos value for a specific source offset (measured in bytes),
-// first add the respective file to the current file set using FileSet.AddFile
-// and then call File.Pos(offset) for that file. Given a Pos value p
-// for a specific file set fset, the corresponding Position value is
-// obtained by calling fset.Position(p).
-//
-// Pos values can be compared directly with the usual comparison operators:
-// If two Pos values p and q are in the same file, comparing p and q is
-// equivalent to comparing the respective source file offsets. If p and q
-// are in different files, p < q is true if the file implied by p was added
-// to the respective file set before the file implied by q.
