15// ----------------------------------------------------------------------------
16// wxIniConfig is a wxConfig implementation which uses MS Windows INI files to
17// store the data. Because INI files don't really support arbitrary nesting of
18// groups, we do the following:
19// (1) in win.ini file we store all entries in the [vendor] section and
20// the value group1/group2/key is mapped to the value group1_group2_key
21// in this section, i.e. all path separators are replaced with underscore
22// (2) in appname.ini file we map group1/group2/group3/key to the entry
23// group2_group3_key in [group1]
24//
25// Of course, it might lead to indesirable results if '_' is also used in key
26// names (i.e. group/key is the same as group_key) and also GetPath() result
27// may be not what you would expect it to be.
28//
29// Another limitation: the keys and section names are never case-sensitive
30// which might differ from wxFileConfig it it was compiled with
31// wxCONFIG_CASE_SENSITIVE option.
32// ----------------------------------------------------------------------------
33
34// for this class, "local" file is the file appname.ini and the global file
35// is the [vendor] subsection of win.ini (default for "vendor" is to be the
36// same as appname). The file name (strAppName parameter) may, in fact,
37// contain the full path to the file. If it doesn't, the file is searched for
38// in the Windows directory.
