releases of Perl are shepherded by a ``pumpking'', a porter
responsible for gathering patches, deciding on a patch-by-patch
feature-by-feature basis what will and will not go into the release.
-For instance, Gurusamy Sarathy is the pumpking for the 5.6 release of
-Perl.
+For instance, Gurusamy Sarathy was the pumpking for the 5.6 release of
+Perl, and Jarkko Hietaniemi is the pumpking for the 5.8 release, and
+Hugo van der Sanden will be the pumpking for the 5.10 release.
In addition, various people are pumpkings for different things. For
instance, Andy Dougherty and Jarkko Hietaniemi share the I<Configure>
-pumpkin, and Tom Christiansen is the documentation pumpking.

there's the Legislature (the porters), the Executive branch (the
It's then up to you to apply these patches, using something like
- # last=`ls -rt1 *.gz | tail -1`
+ # last=`ls -t *.gz | sed q`
# rsync -avz rsync://ftp.linux.activestate.com/perl-current-diffs/ .
# find . -name '*.gz' -newer $last -exec gzcat {} \; >blead.patch
# cd ../perl-current

=head2 Poking at Perl
To really poke around with Perl, you'll probably want to build Perl for
setenv PURIFYOPTIONS "-chain-length=25"
+In Bourne-type shells:
+
+ PURIFY_OPTIONS="..."
+ export PURIFY_OPTIONS
+
+or if you have the "env" utility:
+
+ env PURIFY_OPTIONS="..." ../pureperl ...
+

Purify on Windows NT instruments the Perl binary 'perl.exe'
For further information, see your system's manual pages for pixie and prof.

+
+Those debugging perl with the DDD frontend over gdb may find the
+following useful:
+
+You can extend the data conversion shortcuts menu, so for example you
+can display an SV's IV value with one click, without doing any typing.
+To do that simply edit ~/.ddd/init file and add after:
+
+ ! Display shortcuts.
+ Ddd*gdbDisplayShortcuts: \
+ /t () // Convert to Bin\n\
+ /d () // Convert to Dec\n\
+ /x () // Convert to Hex\n\
+ /o () // Convert to Oct(\n\
+
+the following two lines:
+
+ ((XPV*) (())->sv_any )->xpv_pv // 2pvx\n\
+ ((XPVIV*) (())->sv_any )->xiv_iv // 2ivx
+
+so now you can do ivx and pvx lookups or you can plug there the
+sv_peek "conversion":
+
+ Perl_sv_peek(my_perl, (SV*)()) // sv_peek
+
+(The my_perl is for threaded builds.)
+Just remember that every line, but the last one, should end with \n\
+
+Alternatively edit the init file interactively via:
+3rd mouse button -> New Display -> Edit Menu
+
+Note: you can define up to 20 conversion shortcuts in the gdb
+section.
