-Theorem 5.1 of \cite{MR0283802}, applied $N$ times, allows us
-to choose a homotopy $h:P\times [0,N] \to \Homeo(X)$ with the following properties:
-\begin{itemize}
-\item $h(p, 0) = f(p)$ for all $p\in P$.
-\item The restriction of $h(p, i)$ to $U_0^i \cup \cdots \cup U_i^i$ is equal to the homeomorphism $g$,
-for all $p\in P$.
-\item For each fixed $p\in P$, the family of homeomorphisms $h(p, [i-1, i])$ is supported on

+Theorem 5.1 of \cite{MR0283802}, 
+
 To apply Theorem 5.1 of \cite{MR0283802}, the family $f(P)$ must be sufficiently small,
 and the subdivision mentioned above is chosen fine enough to insure this.
 
-By reparametrizing, we can view $h$ as a homotopy (rel boundary) from $h(\cdot,0) = f: P\to\Homeo(X)$
-to the family
-\[
-	h(\bd(P\times [0,N]) \setmin P\times \{0\}) = h(\bd P \times [0,N]) \cup h(P \times \{N\}) .
-\]
-We claim that the latter family of homeomorphisms is adapted to $\cU$.
-By the second bullet above, $h(P\times \{N\})$ is the constant family $g$, and is therefore supported on the empty set.
-Via an inductive assumption and a preliminary homotopy, we have arranged above that $f(\bd P)$ is
-adapted to $\cU$, which means that $\bd P = \cup_j Q_j$ with $f(Q_j)$ supported on the union of $k-1$
-of the $U_\alpha$'s for each $j$.
-It follows (using the third bullet above) that $h(Q_j \times [i-1,i])$ is supported on the union of $k$ 
-of the $U_\alpha$'s, specifically, the support of $f(Q_j)$ union $U_i$.
