-%% Parse transform for generating record access functions
-%%
-%% This parse transform can be used to reduce compile-time
-%% dependencies in large systems.
-%%
-%% In the old days, before records, Erlang programmers often wrote
-%% access functions for tuple data. This was tedious and error-prone.
-%% The record syntax made this easier, but since records were implemented
-%% fully in the pre-processor, a nasty compile-time dependency was
-%% introduced.
-%%
-%% This module automates the generation of access functions for
-%% records. While this method cannot fully replace the utility of
-%% pattern matching, it does allow a fair bit of functionality on
-%% records without the need for compile-time dependencies.
-%%
-%% Whenever record definitions need to be exported from a module,
-%% inserting a compiler attribute,
-%%
-%%   export_records([RecName, ...])
-%%
-%% causes this transform to lay out access functions for the exported
-%% records:
-%%
-%%   -module(foo)
-%%   -compile({parse_transform, diameter_exprecs}).
-%%
-%%   -record(r, {a, b, c}).
-%%   -export_records([a]).
-%%
-%%   -export(['#info-'/1, '#info-'/2,

-%%            '#new-a'/0, '#new-a'/1,
