* nsWildCard.h: Defines and prototypes for shell exp. match routines
*
* See nsIZipReader.findEntries docs in nsIZipReader.idl for a description of
* the supported expression syntax.
*
* Note that the syntax documentation explicitly says the results of certain
* expressions are undefined. This is intentional to require less robustness
* in the code. Regular expression parsing is hard; the smaller the set of
* features and interactions this code must support, the easier it is to
* ensure it works.
