skipping backslashes at the end of lines

Hi,

this is probably a frequent problem.

What would be the best way to skip backslashes which are 
supposed to break a long line in few shorter lines, like:

	SRC = file1 \
	      file2 \
	      file3 file4

Would $Parse::RecDescent::skip = '\\[ \t]*\n|[ \t]*' work well?

Also for some statements I am using <skip: '[ \t]+'> 
because they are supposed to be on one line, like here:

	export: path <skip: '[ \t]+'> path(?)

What would you please recommend to handle backslashes there?	

Thank you
Alex
