From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001
From: upstream source tree <ports@midipix.org>
Date: Sun, 15 Mar 2015 20:14:05 -0400
Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified
gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream
tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+ * Binders turn functions/functors with two arguments into functors
+ * with a single argument, storing an argument to be applied later.
+ * For example, a variable @c B of type @c binder1st is constructed
+ * from a functor @c f and an argument @c x. Later, B's @c
+ * operator() is called with a single argument @c y. The return
+ * value is the value of @c f(x,y). @c B can be @a called with
+ * various arguments (y1, y2, ...) and will in turn call @c
+ * f(x,y1), @c f(x,y2), ...
+ *
+ * The function @c bind1st is provided to save some typing. It takes the
+ * function and an argument as parameters, and returns an instance of
+ * @c binder1st.
+ *
+ * The type @c binder2nd and its creator function @c bind2nd do the same
+ * thing, but the stored argument is passed as the second parameter instead
+ * of the first, e.g., @c bind2nd(std::minus<float>,1.3) will create a
+ * functor whose @c operator() accepts a floating-point number, subtracts
+ * 1.3 from it, and returns the result. (If @c bind1st had been used,
+ * the functor would perform <em>1.3 - x</em> instead.
+ *
+ * Creator-wrapper functions like @c bind1st are intended to be used in
+ * calling algorithms. Their return values will be temporary objects.
+ * (The goal is to not require you to type names like
+ * @c std::binder1st<std::plus<int>> for declaring a variable to hold the
+ * return value from @c bind1st(std::plus<int>,5).
+ *
+ * These become more useful when combined with the composition functions.
