 Opens a new \SPARK{} verification environment and loads a \texttt{*.siv} file with VCs.
 Alternatively, \texttt{*.vcg} files can be loaded using \isa{\isacommand{spark\_open\_vcg}}.

 Associates a proof function with the given name to a term. The name should be the full name
 of the proof function as it appears in the \texttt{*.fdl} file, including the package prefix.
 This command can be used both inside and outside a verification environment. The latter

-@{rail "@'spark_status' (('(proved)' | '(unproved)')?)"}
+@{rail \<open>
+  @'spark_status' (('(proved)' | '(unproved)')?)
 Outputs the variables declared in the \texttt{*.fdl} file, the rules declared in
 the \texttt{*.rls} file, and all VCs, together with their status (proved, unproved).
 The output can be restricted to the proved or unproved VCs by giving the corresponding
 option to the command.
-@{rail "@'spark_vc' name"}
+@{rail \<open>
+  @'spark_vc' name
 Initiates the proof of the VC with the given name. Similar to the standard
 \isa{\isacommand{lemma}} or \isa{\isacommand{theorem}} commands, this command
 must be followed by a sequence of proof commands. The command introduces the
 hypotheses \texttt{H1} \dots \texttt{H$n$}, as well as the identifiers
 \texttt{?C1} \dots \texttt{?C$m$} corresponding to the conclusions of the VC.
-@{rail "@'spark_end' '(incomplete)'?"}
+@{rail \<open>
+  @'spark_end' '(incomplete)'?
 Closes the current verification environment. Unless the \texttt{incomplete}
 option is given, all VCs must have been proved,
 otherwise the command issues an error message. As a side effect, the command
