+ * some way on a card does not change the backend used to store the card; the
+ * directory is required to do make the changes here.

+ * The following are the core properties that are used:
+ * - Names:
+ *   - FirstName, LastName
+ *   - PhoneticFirstName, PhoneticLastName
+ *   - DisplayName, NickName
+ *   - SpouseName, FamilyName
+ * - PrimaryEmail, SecondEmail
+ * - Home Contact:
+ *   - HomeAddress, HomeAddress2, HomeCity, HomeState, HomeZipCode, HomeCountry
+ *   - HomePhone, HomePhoneType
+ * - Work contact. Same as home, but with `Work' instead of `Home'
+ * - Other Contact:
+ *   - FaxNumber, FaxNumberType
+ *   - PagerNumber, PagerNumberType
+ *   - CellularNumber, CellularNumberType
+ * - JobTitle, Department, Company
+ * - _AimScreenName
+ * - Dates:
+ *   - AnniversaryYear, AnniversaryMonth, AnniversaryDay
+ *   - BirthYear, BirthMonth, BirthDay
+ * - WebPage1 (work), WebPage2 (home)
+ * - Custom1, Custom2, Custom3, Custom4
+ * - Notes
+ * - Integral properties:
+ *   - LastModifiedDate
+ *   - PopularityIndex
+ *   - PreferMailFormat (see nsIAbPreferMailFormat)
+ * - Photo properties:

+ * property.  The checkState method is a useful tool in enforcing
+ * this.  Failure to enforce it may make it impossible to guarantee
+ * that getProperty will do something consistent and reasonable.

+ * when an update fails: the modified card still gets stored and shown to

+ * when you do an update on a card which changes its DN, you have two
+ * operations (rename, then update the other attributes). If the rename

+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.
