\begin{description}
-\item[eapply] \featurelabel{eapply}
+\item[eapply] \featurelabel{eapply} Takes zero or more GNU patch options,
followed by one or more
+ file or directory paths. Processes options and applies all patches found
in specified locations
+ according to Algorithm~\ref{alg:eapply}. If applying the patches fails, it
aborts the build
+ using \t{die}, unless run using \t{nonfatal}, in which case it returns
non-zero exit status.
Only available in EAPIs listed in table~\ref{tab:patch-commands} as
supporting \t{eapply}.
