+    \section2 getenv
+    \code
+    qbs.getenv(name)
+    \endcode
+    Tries to find a variable with the given name in the build environment and returns its value. If
+    no such variable could be found, \c undefined is returned.

+    \code
+    qbs.getHostOS(name)
+    \endcode
+    Returns the name of the operating system on which qbs is running.
