+GENERIC INPUT API
+-----------------
+*re2c* usually operates on input using pointer-like primitives *YYCURSOR*, *YYMARKER*, *YYCTXMARKER* and *YYLIMIT*.
+
+Generic input API (enabled with *--input custom* switch) allows to customize input operations.
+In this mode, *re2c* will express all operations on input in terms of the following primitives:
+
+. *YYPEEK ()* --- get current input character
+. *YYSKIP ()* --- advance to the next character
+. *YYBACKUP ()* --- backup current input position
+. *YYBACKUPCTX ()* --- backup current input position for trailing context
+. *YYRESTORE ()* --- restore current input position
+. *YYRESTORECTX ()* --- restore current input position for trailing context
+. *YYLESSTHAN (n)* --- check if less than *n* input characters are left
+
+This article (http://skvadrik.github.io/aleph_null/posts/re2c/2015-01-13-input_model.html)
+has more details, and you can find some usage examples:
