I might have written the awk a bit differently, but working with what you've got, this should add the leading and trailing square brackets.

Code:
awk  -F "]" -v RS="["  '
        NR == 1 {                              # establish file name just once at beginning
                split( FILENAME, d, ".");
                outfile = d[1] "_out.txt";
                printf( "[" ) >outfile;         # opening bracket to the output
        }
        /\]/{                                   # for each record, print the last one if there, save this one
                if( last )
                        print last >outfile;    # print the one from the last time
                last = $1;                     # save this one til next record is read or end
        }
        END {
                printf( "%s]\n", last ) >outfile;       # print the last line of the matrix and closing bracket
        }
        ' $f

The logic is such that it saves the current line in the matrix and will output it as the next is read. At the end of the input file, the last line of the matrix is printed with the closing bracket.

pod2usage

POD2USAGE(1)						 Perl Programmers Reference Guide					      POD2USAGE(1)

NAME

       pod2usage - print usage messages from embedded pod docs in files

SYNOPSIS

       pod2usage   [-help] [-man] [-exit exitval] [-output outfile] [-verbose level] [-pathlist dirlist] file

OPTIONS AND ARGUMENTS

       -help   Print a brief help message and exit.

       -man    Print this command's manual page and exit.

       -exit exitval
	       The exit status value to return.

       -output outfile
	       The output file to print to. If the special names "-" or ">&1" or ">&STDOUT" are used then standard output is used. If ">&2" or
	       ">&STDERR" is used then standard error is used.

       -verbose level
	       The desired level of verbosity to use:

		   1 : print SYNOPSIS only
		   2 : print SYNOPSIS sections and any OPTIONS/ARGUMENTS sections
		   3 : print the entire manpage (similar to running pod2text)

       -pathlist dirlist
	       Specifies one or more directories to search for the input file if it was not supplied with an absolute path. Each directory path in
	       the given list should be separated by a ':' on Unix (';' on MSWin32 and DOS).

       file    The pathname of a file containing pod documentation to be output in usage message format (defaults to standard input).

DESCRIPTION

       pod2usage will read the given input file looking for pod documentation and will print the corresponding usage message.  If no input file is
       specified then standard input is read.

       pod2usage invokes the pod2usage() function in the Pod::Usage module. Please see "pod2usage()" in Pod::Usage.
