Synopsis
`function pathmatch(filename:string|text,pattern:string|text):boolean`
Arguments

filename | The file name to evaluate
pattern | Matching pattern that may include * (any text of any length) or ? (any single character)

Return value
true if the file name matches the pattern.

Further information
The comparison respects the operating environment conventions and behaviour may differ depending of the operating system. In particular, under Posix systems comparisons are case sensitive; this is not the case on Windows ( i.e. file names are not case sensitive).
