+======Synopsis:======
+$[[regcomp_cs]](<regex pattern>)
+======Technical:======
+This function compiles a regex into a form suitable for passing to the other
+[[regex]] functions. A regex compiled by this function is case-sensitive.
+See the [[regex]] page for more info.
+======Returns:======
+A string representation of a regular expression suitable for further use.
+======Example:======
+<file>
+   @orig_string = "ABC DEF";
+   @pattern = regcomp_cs(abc);
+   if (regerror($pattern)) {
+      xecho -b Error compiling regex: $regerror($pattern);
+   };
+   if (regexec($pattern $orig_string) == 0) {
+      xecho -b It matched!;
+   } else {
+      xecho -b Regex error: $regerror($pattern);
+   };
+   @regfree($pattern);
+</file>
+When run, this will return:
