Hi folks. I work at a company where I don't normally do scripting. I tend to use Perl for like 3 days for some one off scripting need, and then promptly forget everything I learned. I was hoping someone could do this reg exp faster. Say I have a an automatically dumped command line like: 
execute test_number_1 -tex -tex_args -sub_args +debug_dir=./ -sub_args
+ +debug_dir=./ -constraint parity_en,random_en -sub_args '"' ruck=1 '
+"' -constraint dual_en -sub_args -cd -sub_args 2596.slow -sub_args te
+st -seed 1 -tex_args- -opt 1 -tag 2

Since it's difficult to parse what's really going on when it's all a single line, I instead would like to create a script that would take this command line as input and effectively print out something like the below in a kind of tree format: 
execute test_number_1 
    -tex 
        -tex_args 
            -sub_args +debug_dir=./ 
            -sub_args +debug_dir=./ 
            -constraint parity_en,random_en
            -sub_args '"' ruck=1 '"' 
            -constraint dual_en
            -sub_args -cd
            -sub_args 2596.slow 
            -sub_args test 
            -seed 1 
        -tex_args- 
        -opt 1 
        -tag

Can someone help me get started on the most efficient reg exps to do this? There are certain anchors I can see in which to key off of in terms of knowing when to tab, but it's not consistent. For instance, can't always use the "-" reliably to know when to tab over.
