/*
 
The vCard/vCalendar C interface is implemented in the set 
of files as follows:

vcc.y, yacc source, and vcc.c, the yacc output you will use
implements the core parser

vobject.c implements an API that insulates the caller from
the parser and changes in the vCard/vCalendar BNF

port.h defines compilation environment dependent stuff

vcc.h and vobject.h are header files for their .c counterparts

vcaltmp.h and vcaltmp.c implement vCalendar "macro" functions
which you may find useful.

test.c is a standalone test driver that exercises some of
the features of the APIs provided. Invoke test.exe on a
VCARD/VCALENDAR input text file and you will see the pretty
print output of the internal representation (this pretty print
output should give you a good idea of how the internal 
representation looks like -- there is one such output in the 
following too). Also, a file with the .out suffix is generated 
to show that the internal representation can be written back 
in the original text format.

For more information on this API see the readme.txt file
which accompanied this distribution.

/*
Unfortunately, on the Mac (and possibly other platforms) with our current, out-dated
libraries (Plauger), |wchar_t| is defined incorrectly, which breaks vcards.

We can't fix Plauger because it doesn't come with source. Later, when we
upgrade to MSL, we can make this evil hack go away.  In the mean time,
vcards are not allowed to use the (incorrectly defined) |wchar_t| type.  Instead,
they will use an appropriately defined local type |vwchar_t|.
