File names can be case-sensitive or not, the function\rtfsp
\helpref{IsCaseSensitive}{wxfilenameiscasesensitive} allows to determine this.
-The rules for determining if the file name is absolute or relative also depends
-on the file name format and the only portable way to answer to this question is
-to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
-filename is absolute you may use \helpref{MakeAbsolute}{wxfilenamemakeabsolute}.
-There is also an inverse function
-\helpref{MakeRelativeTo}{wxfilenamemakerelativeto} which undoes what
-\helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize} does.
