	find-css: Find one or two words (CSS markups) across CSS, SCSS or LESS files
	          in the folder passed as first parameter.
	
	Both expressions (literal or regex expressions) can be away each other
	up to 4 lines, or `-C LINES` (the `-C` parameter is optional and
	must be the last one).

	Also temp folders are omitted in the search.

	Usage: find-css LOCATION EXPR1 [EXPR2] [-C NUMLINES]
	
	Usage example:
       
	    $ find-css . "#header" ".menu" -C 8
	EOF
  exit -1
fi

# To skip minified markup files, lines content are taken into account up
# to this number of chars, including the filepath output at the beginning,
# so extra ~40 chars is recommended
