-When a pattern with <b>push</b> modifier is successfully compiled, it is pushed
-onto a stack of compiled patterns, and <b>pcre2test</b> expects the next line to
-contain a new pattern (or command) instead of a subject line. By contrast,
-the <b>pushcopy</b> modifier causes a copy of the compiled pattern to be
-stacked, leaving the original available for immediate matching. By using
-<b>push</b> and/or <b>pushcopy</b>, a number of patterns can be compiled and
-retained. These modifiers are incompatible with <b>posix</b>, and control
-modifiers that act at match time are ignored (with a message) for the stacked
-patterns. The <b>jitverify</b> modifier applies only at compile time.
+Note that "serialization" in PCRE2 does not convert compiled patterns to an 
+abstract format like Java or .NET. It just makes a reloadable byte code stream.
+Hence the restrictions on reloading mentioned above.
