+
+Bare Bones has three simple commands for manipulating a variable:
+
+clear name;
+incr name;
+decr name;
+...which respectively sets variable name to zero, increments it by one and decrements it by one.
+
+The language also contains one control sequence, a simple loop:
+
+while name not 0 do;
+...
+...
+end;
+... where name is a variable. Note that variables need not be declared before they are used and must be non-negative integers. Statements are delimited by the ; character.
+
+Note that while loops must be terminated by an end statement, but that they can be nested.''',
