37
// This class manages properties and their serialization.
38
// What you do is this:
39
//   1. Declare the CProperties object
40
//   2. Call one or more "Add" functions to associate variables with names
41
//   3. Call one of the "Load" or "Save" functions to load or save the values
42
// There are three ways in which the "Load" or "Save" functions operate
43
//   a. Loading/saving to/from a file [LoadFromFile/SaveToFile]
44
//      In this case the contents of the file will look like
45
//        name1=value1
46
//        name2=value2
47
//        ...
48
//   b. Loading/saving to/from a command string [LoadFromCommandString/MakeCommandString]
49
//      In this case the contents of the string will look like
50
//        -name1=value1 -name2=value2 ...
51
//   c. Loading/saving to/from the registry [LoadFromRegistry/SaveToRegistry]
52
//      In this case the registry will contain a set of values (name1, name2,...) each of whose
53
//      value data is the corresponding value.
