* This file contains mathoms, various binary artifacts from previous

+ * versions of Perl which we cannot completely remove from the core
+ * code. There are two reasons functions should be here:
+ *
+ * 1) A function has been replaced by a macro within a minor release,
+ * so XS modules compiled against an older release will expect to
+ * still be able to link against the function
+ * 2) A function Perl_foo(...) with #define foo Perl_foo(aTHX_ ...)
+ * has been replaced by a macro, e.g. #define foo(...) foo_flags(...,0)
+ * but XS code may still explicitly use the long form, i.e.
+ * Perl_foo(aTHX_ ...)
+ *
+ * This file can't just be cleaned out periodically, because that would break
+ * builds with -DPERL_NO_SHORT_NAMES
+ *
+ * NOTE: ALL FUNCTIONS IN THIS FILE should have an entry with the 'b' flag in
+ * embed.fnc.
+ *
+ * To move a function to this file, simply cut and paste it here, and change
+ * its embed.fnc entry to additionally have the 'b' flag. If, for some reason
+ * a function you'd like to be treated as mathoms can't be moved from its
+ * current place, simply enclose it between
*
- * SMP - Oct. 24, 2005
+ * #ifndef NO_MATHOMS
