+  \class Qtx::Localizer
+  \brief Localization helper
+
+  This helper class can be used to solve the localization problems,
+  usually related to the textual files reading/writing, namely when
+  floating point values are read / written with API functions.
+  The problem relates to such locale specific settings as decimal point
+  separator, thousands separator, etc.
+  
+  To use the Localizer class, just create a local variable in the beginning
+  of the code where you need to read / write data from textual file(s).
+  The constructor of the class forces setting "C" locale temporariy.
+  The destructor switches back to the initial locale.
+
+  \code
+  Qtx::Localizer loc;
+  readSomething();
+  writeSomething();
+  \endcode
