Acronym Hyphenation

The acronym package is quite useful. However, the hyphenation is prevented which might lead to overfull boxes. To enable the hyphenation for the acronym package, add the following somewhere after \include{acronym}.

\makeatletter
\renewcommand*\AC@get[3]{%
\ifx#1\relax
  \PackageWarning{acronym}{Acronym `#3' is not defined}%
  \textbf{#3!}%
\else
  \expandafter#2#1%
\fi}
\makeatother
