$msar([c][i][g][r]/[<search>/<replace>/]*<text>)

The arguments are composed of:

1. zero or more of the options c, i, g, and r,
2. a delimiter which can be any character other than c, i, g, or r, and is customarily a forward-slash,
3. ZERO OR MORE SETS OF SUBSTITUTIONS:
   • some text (<search>) that may not contain the delimiter to be removed,
   • a delimiter; the same as (2),
   • some text (<replace>) that may not contain the delimiter to be inserted in place of (3a),
   • a delimiter; the same as (2),
4. a string of text (<text>) that MAY NOT contain the delimiter to be transformed.

No matter what, <text> is always the text that follows the final delimiter. If properly formed, there should always be an odd number of delimiters in the arguments. But if there is an even number of delimiters, this would result in a substutition with a <search> but no <replace>. This <search> would be ignored as a syntax error.

In its simple form, the string <text> is returned with the first instance of each of the <search> strings replaced with each of the corresponding <replace> strings. The matching of <search> is case-insensitive by default.

The options modify this behavior:

the resultant string

$msar(/as/xy/asdf)                 returns "xydf"
$msar(/as/xy/yd/42/asdf)           returns "x42f"
$msar(/e/he/pi/ll/c/o/epic)        returns "hello"
