Why don't you give it a try? Every fieldname will have its own array element.
EDIT: Oh, got you now. shells don't have those structures. Recent shells with associative arrays might allow for an approach comig close...

Can you explain this condition?
Code:
if (CNT==1 && !/^ *$/)

CNT represents the "level" of "{...}" nestings. So, if the level is 1 deep, and if there's more than an "empty" (nothing but spaces) line, print that. This is, of course, heavily depending on the structure of your file. If all the info were written in a single line, that logic would be doomed.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

	   No operation mode. Actual execution of the essential shell commands which would be executed is suppressed.

       -w, --warning

	%install
	    shtool subst -v -n 
		-e 's;^(prefix=).*;1 $RPM_BUILD_ROOT%{_prefix};g' 
		-e 's;^(sysconfdir=).*;1 $RPM_BUILD_ROOT%{_prefix}/etc;g' 
		`find . -name Makefile -print`
	    make install

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

SEE ALSO

       shtool(1), sed(1).
