-
-This file contains the documentation of the perl public API generated by
-F<embed.pl>, specifically a listing of functions, macros, flags, and variables
-that may be used by extension writers. L<At the end|/Undocumented functions>
-is a list of functions which have yet to be documented. The interfaces of
-those are subject to change without notice. Any functions not listed here are
-not part of the public API, and should not be used by extension writers at
-all. For these reasons, blindly using functions listed in proto.h is to be
-avoided when writing extensions.
-
-Note that all Perl API global variables must be referenced with the C<PL_>
-prefix. Some macros are provided for compatibility with the older,
-unadorned names, but this support may be disabled in a future release.
-
-Perl was originally written to handle US-ASCII only (that is characters
-whose ordinal numbers are in the range 0 - 127).
-And documentation and comments may still use the term ASCII, when
-sometimes in fact the entire range from 0 - 255 is meant.
-
-Note that Perl can be compiled and run under EBCDIC (See L<perlebcdic>)
-or ASCII. Most of the documentation (and even comments in the code)
-ignore the EBCDIC possibility.
-For almost all purposes the differences are transparent.
-As an example, under EBCDIC,
-instead of UTF-8, UTF-EBCDIC is used to encode Unicode strings, and so
-whenever this documentation refers to C<utf8>
-(and variants of that name, including in function names),
-it also (essentially transparently) means C<UTF-EBCDIC>.
-But the ordinals of characters differ between ASCII, EBCDIC, and
-the UTF- encodings, and a string encoded in UTF-EBCDIC may occupy more bytes
-than in UTF-8.
-
-The listing below is alphabetical, case insensitive.

+|
+|=head1 DESCRIPTION
+|X<Perl API> X<API> X<api>
+|
+|This file contains most of the documentation of the perl public API, as
+|generated by F<embed.pl>. Specifically, it is a listing of functions,
+|macros, flags, and variables that may be used by extension writers. Some
+|specialized items are instead documented in $specialized_docs.
+|
+|L<At the end|/Undocumented functions> is a list of functions which have yet
+|to be documented. Patches welcome! The interfaces of these are subject to
+|change without notice.
+|
+|Anything not listed here is not part of the public API, and should not be
+|used by extension writers at all. For these reasons, blindly using functions
+|listed in proto.h is to be avoided when writing extensions.
+|
+|In Perl, unlike C, a string of characters may generally contain embedded
+|C<NUL> characters. Sometimes in the documentation a Perl string is referred
+|to as a "buffer" to distinguish it from a C string, but sometimes they are
+|both just referred to as strings.
+|
+|Note that all Perl API global variables must be referenced with the C<PL_>
+|prefix. Again, those not listed here are not to be used by extension writers,
+|and can be changed or removed without notice; same with macros.
+|Some macros are provided for compatibility with the older,
+|unadorned names, but this support may be disabled in a future release.

+|sometimes in fact the entire range from 0 - 255 is meant.
+|
+|The non-ASCII characters below 256 can have various meanings, depending on
+|various things. (See, most notably, L<perllocale>.) But usually the whole
+|range can be referred to as ISO-8859-1. Often, the term "Latin-1" (or
+|"Latin1") is used as an equivalent for ISO-8859-1. But some people treat
+|"Latin1" as referring just to the characters in the range 128 through 255, or
+|somethimes from 160 through 255.
+|This documentation uses "Latin1" and "Latin-1" to refer to all 256 characters.
+|
+|Note that Perl can be compiled and run under either ASCII or EBCDIC (See
+|L<perlebcdic>). Most of the documentation (and even comments in the code)
+|ignore the EBCDIC possibility.
+|For almost all purposes the differences are transparent.
+|As an example, under EBCDIC,
+|instead of UTF-8, UTF-EBCDIC is used to encode Unicode strings, and so
+|whenever this documentation refers to C<utf8>
+|(and variants of that name, including in function names),
+|it also (essentially transparently) means C<UTF-EBCDIC>.
+|But the ordinals of characters differ between ASCII, EBCDIC, and
+|the UTF- encodings, and a string encoded in UTF-EBCDIC may occupy a different
+|number of bytes than in UTF-8.
+|
+|The listing below is alphabetical, case insensitive.
