 SYNOPSIS
+        #include <regexp.h>
+
         string * regexplode(string text, string pattern)
+        string * regexplode(string text, string pattern, int opt)
 
-BESCHREIBUNG
-        regexplode() verhaelt sich aehnlich wie explode(), akzeptiert aber
-        auch regulaere Ausdruecke als Trennzeichen. Im Ergebnisarray ist
-        jedes zweite Element ein Trennzeichen.
+DESCRIPTION
+        This function is similar to explode but accepts a regular
+        expression <pattern> as delimiter (interpreted according to <opt>
+        if given).
 
-GESCHICHTE
-        Eingefuehrt in 3.2@61.
+        If flag RE_OMIT_DELIM is not set in <opt>, then every second element
+        in the result vector will be the text that matched the delimiter.
+        If the flag is set, then the result vector will contain only
+        the text between the delimiters.
 
-SIEHE AUCH
-        explode(E), regexp(E), regreplace(E)
+EXAMPLES
+        regexplode("abcdef", "cde")                -> ({ "ab", "cde", "f" })
+        regexplode("abcdef", "cde", RE_OMIT_DELIM) -> ({ "ab", "f" })
+
+HISTORY
+        Introduced in 3.2@61.
+        LDMud 3.3 added the optional <opt> argument and the RE_OMIT_DELIM
+          flag.
+        Since 3.5.0 a error is raised if RE_PCRE is specified in <opt>, but
+        the driver lacks PCRE support.
