17=head1 INTRODUCTION

19Perl history in brief, by Larry Wall:
20
a3cb178b
GS
21 Perl 0 introduced Perl to my officemates.
22 Perl 1 introduced Perl to the world, and changed /\(...\|...\)/ to
d516a115 23 /(...|...)/. \(Dan Faigin still hasn't forgiven me. :-\)
cac726e9

24 Perl 2 introduced Henry Spencer's regular expression package.
25 Perl 3 introduced the ability to handle binary data (embedded nulls).
26 Perl 4 introduced the first Camel book. Really. We mostly just
d516a115 27 switched version numbers so the book could refer to 4.000.
cac726e9 28 Perl 5 introduced everything else, including the ability to
d516a115 29 introduce everything else.

37=head2 PUMPKIN?
38
39[from Porting/pumpkin.pod in the Perl source code distribution]
40
41Chip Salzenberg gets credit for that, with a nod to his cow orker,
42David Croy. We had passed around various names (baton, token, hot
43potato) but none caught on. Then, Chip asked:
44
45[begin quote]
46
47 Who has the patch pumpkin?
48
49To explain: David Croy once told me once that at a previous job,
50there was one tape drive and multiple systems that used it for backups.
51But instead of some high-tech exclusion software, they used a low-tech
52method to prevent multiple simultaneous backups: a stuffed pumpkin.
53No one was allowed to make backups unless they had the "backup pumpkin".
54
55[end quote]
56
57The name has stuck. The holder of the pumpkin is sometimes called
193fb0af
GS
58the pumpking (keeping the source afloat?) or the pumpkineer (pulling
59the strings?).

412changed lines for 424 kilobytes. Just the lines themselves are
