+Support for 'conditional compilation' in a C-style manner of PyCell code:
+
+```
+    #ifdef name (|| name)*
+        ...some code...
+    #else
+        ...some other code...
+    #endif
+```
+
+The #ifdef-block is executed (name is considered as defined) if
+  1. An environment variable name can be found case-insentive, or
+  2. The name can be found case-insentive as part of a process name of the process chain beginnig at
+     the current process upwards through all parent processes.
+otherwise the #else-block is executed
+
+The current process chain will be dumped if the environment variable 'IHP\_PYCELL\_LIB\_PRINT\_PROCESS_TREE'
+is set.
+
+The list of names which are used in an #ifdef-statement and are considered as 'defined' will be dumped
+if the environment variable 'IHP\_PYCELL\_LIB\_PRINT\_DEFINES\_SET' is set.
+
+On non-windows platforms using the 'conditional PyCell compilation' feature, the Python library psutil must be installed.
