Those lines could be fed into the shell raw and work. You can just read lines, and wrap an eval around them, which tells it to parse and evaluate that line as if it'd read it from the script itself..

Code:
while read LINE
do
        [ -z "$LINE" ] && break;        # Ignore blank lines
        Name="" Arg1="" Arg2="" Arg3="" # Clear out old variables
        eval "$LINE"                    # Assign variables
        echo $Name $Arg1 $Arg2 $Arg3    # Tada
done < cfgfile

Code:
$ ./rdconfig.sh
line1 valueA valueB valueC
line2 valueD
line3 valueE valueF
line4 valueG valueH
$

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
