-// URL filename encoder goals:
-//
-// 1. Allow URLs with arbitrary path-segment length, generating filenames
-//    with a maximum of 128 characters.
-// 2. Provide a somewhat human readable filenames, for easy debugging flow.
-// 3. Provide reverse-mapping from filenames back to URLs.
-// 4. Be able to distinguish http://x from http://x/ from http://x/index.html.
-//    Those can all be different URLs.
-// 5. Be able to represent http://a/b/c and http://a/b/c/d, a pattern seen
-//    with Facebook Connect.
-//
-// We need an escape-character for representing characters that are legal
-// in URL paths, but not in filenames, such as '?'.
-//
-// We can pick any legal character as an escape, as long as we escape it too.
-// But as we have a goal of having filenames that humans can correlate with
-// URLs, we should pick one that doesn't show up frequently in URLs. Candidates
-// are ~`!@#$%^&()-=_+{}[],. but we would prefer to avoid characters that are
-// shell escapes or that various build tools use.
-//
-// .#&%-=_+ occur frequently in URLs.
-// <>:"/\|?* are illegal in Windows
-//   See http://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx
-// ~`!$^&(){}[]'; are special to Unix shells
-// In addition, build tools do not like ^@#%
-//
-// Josh took a quick look at the frequency of some special characters in
-// Sadeesh's slurped directory from Fall 09 and found the following occurances:
-//
-//   ^   3               build tool doesn't like ^ in testdata filenames
-//   @   10              build tool doesn't like @ in testdata filenames
-//   .   1676            too frequent in URLs
-//   ,   76              THE WINNER
-//   #   0               build tool doesn't like it
-//   &   487             Prefer to avoid shell escapes
-//   %   374             g4 doesn't like it
-//   =   579             very frequent in URLs -- leave unmodified
-//   -   464             very frequent in URLs -- leave unmodified
-//   _   798             very frequent in URLs -- leave unmodified
-//
-//
-// The escaping algorithm is:
-//  1) Escape all unfriendly symbols as ,XX where XX is the hex code.
-//  2) Add a ',' at the end (We do not allow ',' at end of any directory name,
-//     so this assures that e.g. /a and /a/b can coexist in the filesystem).
-//  3) Go through the path segment by segment (where a segment is one directory
-//     or leaf in the path) and
-//     3a) If the segment is empty, escape the second slash. i.e. if it was
-//         www.foo.com//a then we escape the second / like www.foo.com/,2Fa,
-//     3a) If it is "." or ".." prepend with ',' (so that we have a non-
-//         empty and non-reserved filename).
-//     3b) If it is over 128 characters, break it up into smaller segments by
-//         inserting ,-/ (Windows limits paths to 128 chars, other OSes also
-//         have limits that would restrict us)
-//
-// For example:
-//     URL               File
-//     /                 /,
-//     /index.html       /index.html,
-//     /.                /.,
-//     /a/b              /a/b,
-//     /a/b/             /a/b/,
-//     /a/b/c            /a/b/c,   Note: no prefix problem
-//     /u?foo=bar        /u,3Ffoo=bar,
-//     //                /,2F,
-//     /./               /,./,
-//     /../              /,../,
-//     /,                /,2C,
-//     /,./              /,2C./,
-//     /very...longname/ /very...long,-/name   If very...long is about 126 long.
-
-// NOTE: we avoid using some classes here (like FilePath and GURL) because we
-//       share this code with other projects externally.
