-kconfigdata.h contains definitions of the data formats used by kconfig.
-
-Configuration entries are stored as "KEntry". They are indexed with "KEntryKey".
-The primary store is a "KEntryMap" which is defined as a QMap from "KEntryKey"
-to "KEntry"
-
-KEntry's are stored in order in the KEntryMap. The most significant sort
-criteria is mGroup. This means that all entries who belong in the same group,
-are grouped in the QMap as well.
-
-The start of a group is indicated with a KEntryKey with an empty mKey and a
-dummy KEntry. This allows us to search for the start of the group and then to
-iterate until we end up in another group. That way we will find all entries
-of a certain group.
-
-Entries that are localised with the _current_ locale are stored with bLocal
-set to true. Entries that are localised with another locale are either not
-stored at all (default), or with the localization as part of the key (when
-reading a file in order to merge it).
-[WABA: Does it make sense to keep both localized and non-localised around?
-Can't we just let the localised version override the non-localised version?]
-
-Currently the localization bit is the least significant sort criteria, that
-means that the localised version always follows the non-localised version
-immediately.
-
-<Changed for KDE 3.0>
-Entries that are being read from a location other than the location to
-which is written back are marked as "default" and will be added both as
-normal entry as well as an entry with the key marked as default.
-
-When entries are written to disk, it is checked whether the entry to write
-is equal to the default, if so the entry will not be written. The default
-entry always follows directly after the normal entry, due to the sorting.
-(After that the localised version follows)
-
-When entries are written to disk, it is checked whether the entry to write
-is equal to the default, if so the entry will not be written.
-</Changed>
-
-Open question:
-Should unmodified entries that are written back be compared with the default
-too? This seems to be mostly a transition issue.
-
-<Changed during KDE 3.0 / 3.2>
-Extra functions:
-
-bool entryIsImmutable(key); // Can entry be modified?
-bool hasDefault(key); // Is there a system wide default set for the entry?
-void revertToDefault(key); // Restore to default
-void deleteEntry(key); // Remove entry
-
-Note that there is a subtle difference between revertToDefault() and deleteEntry().
-revertToDefault() will change the entry to the default value set by the system
-administrator (Via e.g. $TDEDIR/share/config) or, if no such default was set,
-non-existant.
-deleteEntry() will make the entry non-existant.
-
-Entries are marked "immutable" if the key is followed by [$i]. This means
-that a user can not override these entries.
-
-Entries can be marked as deleted if they are followed by [$d]. This
-is needed if the system administrator has specified a default value but the
-entry was deleted (made 'non-existant'). In that case we can't just leave
-the entry out since that would mean we get the default from the system
-administrator back the next time we read the file.
-</changed>
-
-When an entry is read with readEntry(key, defaultValue), non-existing
-entries will return "defaultValue" while hasKey(key) will return "false"
-for such entries.
-
-Currently all entries are stored in memory. When TDEConfig is "sync()'ed"
-it reads the file that it is about to overwrite (for the second time), it
-then merges in the entries it has in memory and writes the result back to
-the file. It does NOT update its map of entries in memory with the entries
-(re)read from disk. It only updates the entries in memory when
-"reparseConfiguration()" is called.
-
-
-Open Question: The standard writeEntry() function returns the original value,
-is this needed? Nobody seems to use it.
-
-Open Question: The bPersistent flag doesn't seem to be used... could it be removed?
-
-Open Question: Is the bNLS flag needed? Localised entries seem to be mostly
-useful for default files, are they ever created by the user itself?
-
-Open Question: Would it be worthwhile to lock a user option that is equal to the
-default so that it doesn't change when the default changes?

-KDE3.0 Changes
-==============
-
-*) writeEntry now returns void instead of QString.
-*) deleteEntry functions added

-TDEConfig XT
-==========
-
-My buzzword picker offered TDEConfig XT ("eXtended Technology") and TDEConfig NG
-("Next Generation"). Since the planned changes are ment to be evolutionary
-rather than revolutionary, TDEConfig NG was dropped.
-
-Goals
-=====
-
-* Have the default value for config entries defined in 1 place. Currently it is
-not uncommon to have them defined in three places:
- 1) In the application that reads the setting in order to use it
- 2) In the settings dialog when reading the setting
- 3) In the settings dialog when selecting "Use defaults".
-
-* Provide type-information about config entries to facilate "KConfEdit" like
-tools. Ideally type-information also includes range-information; this is even
-mandatory if enums become an explicit type.
-
-* Facilitate the documentation of config entries.
-
-
-Instead of relying on the defaults that are hard-coded in the application,
-rely on default configuration files being installed in $TDEDIR. The technical
-changes required for this are very minimal, it is mostly a change in policy.
-
-Type information can be provide by preceding every entry with a formalized
-comment.
-
-Work to be done:
-* TDEConfig needs to be extended to provide access to the default values provided
-by the default config files. TDEConfig already stores this information internally.
-(DONE)
-* A formal comment structure needs to be designed that can convey type-information.
-Preferably in such a way that it is easily parsable by both machine and user.
-* TDEConfig needs to be extended, or another class created, that is able to parse
-the formalized comments.
-* A tool needs to be developed that can assist developers with the generation
-and verification of default configuration files including type-information.
-
-Drawbacks:
-* We rely on default configuration files being properly installed.
-* The user can break applications by making improper modifications to these
-files.
-* It is not possible to store defaults settings in a config file that are
-of a dynamic nature. Examples are settings derived from other settings,
-e.g. a color setting could be derived from the current color theme, or
-e.g. the default high score user name which is determined by the user
-currently logged in.
-
-
-Some random ideas:
-* The format of the entries would be something like this:
-
-[Mail Settings]
-#!Type=string
-#!Description=SMTP server to use for sending mail
-#!Description[nl]=SMTP server voor het versturen van mail
-Host=wantelbos.zogje.fr
-
-- the type could be subclassed more, e.g. strings can be "email", "hostname",
- "url", etc.
-
-- having translations in these files is very arguable. external po's would be
- better.

-TDEConfigBase: defines API for generic config class
-
-TDEConfig: functional generic config class that supports merging of cascaded
- configuration files
-
-KSimpleConfig: functional generic config class without support for cascading
- configuration files.
-
-TDEConfigBackend: defines API for config backend, t.i. the actual handling
- of the storage method and storage format.
-
-TDEConfigINIBackend: the standard (and only one so far) class that implements
- the config backend using the file-based .INI format
- for configuration files
-
-TDEConfigSkeleton: base class for deriving classes that store application
- specific options providing type-safety and single-point
- defaults.
-
-MyConfig: An application specific class that offers configuration options
- to the applications via variables or accessor functions and that
- handles type-safety and defaults. MyConfig is just an example
- name, the application developer choses the actual name.
-
-myapp.kcfg: File describing the configuration options used by a specific
- application. myapp.kcfg is just an example name, the application
- developer choses the actual name.
-
-myconfig.kcfg-codegen: Implementation specific code generation instructions
- for the MyConfig class. myconfig.kcfg-codegen is
- just an example name, the application developer
- choses the actual name.
-
-TDEConfigDialogManager: Class that links widgets in a dialog up with their
- corresponding confguration options in a configuration
- object derived from TDEConfigSkeleton.
-
-MyConfigWidget: Dialog generated from a .ui description file. Widget names
- in the dialog that start with "kcfg_" refer to configuration
- options.
