+/** \defgroup exception System exceptions
+
+    The senf::SystemException class and it's derived class template senf::ErrnoException are used to
+    signal generic system failures based on \c errno codes. 
+
+    senf::SystemException is a generic \c errno based exception which carries an error number and
+    origin information. senf::ErrnoException is a derived class specialized for a specific error
+    code. This simplifies managing error conditions:
+
+    \code
+    try {
+        something.open(path);
+        // ...
+    }
+    catch (senf::ErrnoException<ENOFILE> & e) {
+        // Create new file
+    }
+    catch (senf::SystemException & e) {
+        // Catch all other system exceptions
+        std::cerr << "Error accessing '" << path << "': " << e.what() << std::endl;
+    }
+    \endcode
+
+    This exception is normally thrown using the senf::throwErrno() helper:
+
+    \code
+    if ((fd = ::open(path.c_str(), O_RDWR)) < 0)
+        senf::throwErrno("::open()");
+    \endcode
+
+    The senf::throwErrno() helper will throw the correct exception class based on some \c errno
+    value.
