-/*
- FileConfig derives from BaseConfig and implements file based config class,
- i.e. it uses ASCII disk files to store the information. These files are
- alternatively called INI, .conf or .rc in the documentation. They are
- organized in groups or sections, which can nest (i.e. a group contains
- subgroups, which contain their own subgroups &c). Each group has some
- number of entries, which are "key = value" pairs. More precisely, the format
- is:
-
- # comments are allowed after either ';' or '#' (Win/UNIX standard)
-
- # blank lines (as above) are ignored
-
- # global entries are members of special (no name) top group
- written_for = wxWindows
- platform = Linux
-
- # the start of the group 'Foo'
- [Foo] # may put comments like this also
- # following 3 lines are entries
- key = value
- another_key = " strings with spaces in the beginning should be quoted, \
- otherwise the spaces are lost"
- last_key = but you don't have to put " normally (nor quote them, like here)
-
- # subgroup of the group 'Foo'
- # (order is not important, only the name is: separator is '/', as in paths)
- [Foo/Bar]
- # entries prefixed with "!" are immutable, i.e. can't be changed if they are
- # set in the system-wide config file
- !special_key = value
- bar_entry = whatever
-
- [Foo/Bar/Fubar] # depth is (theoretically :-) unlimited
- # may have the same name as key in another section
- bar_entry = whatever not
-
- You have {read/write/delete}Entry functions (guess what they do) and also
- setCurrentPath to select current group. enum{Subgroups/Entries} allow you
- to get all entries in the config file (in the current group). Finally,
- flush() writes immediately all changed entries to disk (otherwise it would
- be done automatically in dtor)
-
- FileConfig manages not less than 2 config files for each program: global
- and local (or system and user if you prefer). Entries are read from both of
- them and the local entries override the global ones unless the latter is
- immutable (prefixed with '!') in which case a warning message is generated
- and local value is ignored. Of course, the changes are always written to local
- file only.

+ This is a bit complicated, so let me explain it in details. All lines that
+ were read from the local file (the only one we will ever modify) are stored
+ in a (doubly) linked list. Our problem is to know at which position in this
+ list should we insert the new entries/subgroups. To solve it we keep three
+ variables for each group: m_pLine, m_pLastEntry and m_pLastGroup.
+
+ m_pLine points to the line containing "[group_name]"
+ m_pLastEntry points to the last entry of this group in the local file.
+ m_pLastGroup subgroup
+
+ Initially, they're NULL all three. When the group (an entry/subgroup) is read
+ from the local file, the corresponding variable is set. However, if the group
+ was read from the global file and then modified or created by the application
+ these variables are still NULL and we need to create the corresponding lines.
+ See the following functions (and comments preceding them) for the details of
+ how we do it.
+
+ Also, when our last entry/group are deleted we need to find the new last
+ element - the code in DeleteEntry/Subgroup does this by backtracking the list
+ of lines until it either founds an entry/subgroup (and this is the new last
+ element) or the m_pLine of the group, in which case there are no more entries
+ (or subgroups) left and m_pLast<element> becomes NULL.
+
+ NB: This last problem could be avoided for entries if we added new entries
+ immediately after m_pLine, but in this case the entries would appear
+ backwards in the config file (OTOH, it's not that important) and as we
+ would still need to do it for the subgroups the code wouldn't have been
+ significantly less complicated.
