+# Compare source codes for cheating
+My diploma for Bachelor degree in Moscow Aviation Institute.
+
+This tool can be used for compare sources in university/schools for cheating.
+
+Available source code comprasion:
+* C/C++
+
+In future:
+* Python
+* Java
+* Pascal/Delphi
+
+You can get sources from some testing systems:
+* ejudge (TODO)
+* Codeforces (TODO)
+
+## Install
+
+## Usage
+
+## How it works
+
+Now it's compare two Abstract Syntax Tree.
+The problem is to get good AST for compare. AST for C++ code generates by clang bindings for python.
