-/*
-  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.

+  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.
