-
-**Building for windows is not mainteined, but was possible in the past, you can try, but it probably won't work**

-The best way to acquire library `lmdb` and `boost` is through Msys2.
-
-First install Msys2, and then install `mingw-w64-x86_64-lmdb` and `mingw-w64-x86_64-boost` by pacman.
-
-Then you need to provide the cmake cache entry when calling cmake for configuration:

 - `CMAKE_BUILD_TYPE` - `Debug` just builds showing all warnings, `Release` builds with no warnings and applies optimizations (default is `Debug`)
 - `SYSTEM_QXMPP` - `True` tries to link against `qxmpp` installed in the system, `False` builds bundled `qxmpp` library (default is `True`)
-- `SYSTEM_LMDBAL` - `True` tries to link against `LMDABL` installed in the system, `False` builds bundled `LMDBAL` library (default is `True`)
 - `WITH_KWALLET` - `True` builds the `KWallet` capability module if `KWallet` is installed and if not goes to `False`. `False` disables `KWallet` support (default is `True`)
 - `WITH_KIO` - `True` builds the `KIO` capability module if `KIO` is installed and if not goes to `False`. `False` disables `KIO` support (default is `True`)

+ @ short Simple encrypt*ion and decryption of strings and byte arrays
+ 
+ This class provides a simple implementation of encryption and decryption
+ of strings and byte arrays.
+ 
+ @warning The encryption provided by this class is NOT strong encryption. It may
+ help to shield things from curious eyes, but it will NOT stand up to someone
+ determined to break the encryption. Don't say you were not warned.
+ 
+ The class uses a 64 bit key. Simply create an instance of the class, set the key,
+ and use the encryptToString() method to calculate an encrypted version of the input string.
+ To decrypt that string again, use an instance of SimpleCrypt initialized with
+ the same key, and call the decryptToString() method with the encrypted string. If the key
+ matches, the decrypted version of the string will be returned again.
+ 
+ If you do not provide a key, or if something else is wrong, the encryption and
+ decryption function will return an empty string or will return a string containing nonsense.
+ lastError() will return a value indicating if the method was succesful, and if not, why not.
+ 
+ SimpleCrypt is prepared for the case that the encryption and decryption
+ algorithm is changed in a later version, by prepending a version identifier to the cypertext.

-      Squawk is a lightweight XMPP desktop messenger.
-      The primary objective of this project is to offer
-      you a fast and user-friendly messaging experience
-      that closely aligns with your system’s style, while
-      also minimizing resource consumption.
-    </p>
-    <p>
-      Squawk is still at a very early stage and might not suit
-      everyone but you are welcome to try it out.
