+__END__
+
+Documentation is mostly by example.
+
+Setup:
+
+  * uncomment the line
+        'macros',
+    in the ENABLE list in ~/.gitolite.rc
+
+Notes on macro definition:
+
+  * the keywords 'macro' and 'end' should start on a new line
+  * the first word after 'macro' is the name of the macro, and the rest, until
+    the 'end', is the body
+
+Notes on macro use:
+
+  * the macro name should be the first word on a line
+  * the rest of the line is used as arguments to the macro
+
+Example:
+
+    if your conf contains:
+
+        macro foo repo aa-%1
+            RW  =   u1 %2
+            R   =   u2
+        end
+
+        foo 1 alice
+        foo 2 bob
+
+    this will effectively turn into
+
+        repo aa-1
+            RW  =   u1 alice
+            R   =   u2
+
+        repo aa-2
+            RW  =   u1 bob
+            R   =   u2
