Ruby regexp help

I need help to remove the string /* s */ (comments in .c and .h files) from some files using Ruby. Is it correct to use gsub to do this. I know 开发者_运维技巧that this string is always placed at the beginning av a line.

thx.

str.gsub(/^\/\*.*?\*\// , '')

Doesn't look nice, but should do it.
