This is patch perl5.003_06.pat to perl version 5.003_05.
This takes you from 5.003_05 to 5.003_06.

To apply this patch, run the above commands,
cd to your perl source directory and then type

        patch -p1 -N < perl5.003_06.pat

The changes are described after each /^Index:/ line below.  This is
designed so you can examine each change with a command such as

        csplit -k perl5.003_06.pat '/^Index:/' '{999}'

(Of course, since there are more than 100 Index entries, your
csplit may complain, since many csplit's have an arbitrary limit of 100
files.  Still, you can manually split the file or roll your own.)

Patch and enjoy,

-.SH NAME
-a2p - Awk to Perl translator
-.SH SYNOPSIS
-.B a2p [options] filename
-.SH DESCRIPTION
-.I A2p
-takes an awk script specified on the command line (or from standard input)
-and produces a comparable
-.I perl
-script on the standard output.
-.Sh "Options"
-Options include:
-.TP 5
-.B \-D<number>
-sets debugging flags.
-.TP 5
-.B \-F<character>
-tells a2p that this awk script is always invoked with this -F switch.
-.TP 5
-.B \-n<fieldlist>
-specifies the names of the input fields if input does not have to be split into
-an array.
-If you were translating an awk script that processes the password file, you
-might say:
-.sp
-       a2p -7 -nlogin.password.uid.gid.gcos.shell.home
-.sp
-Any delimiter can be used to separate the field names.
-.TP 5
-.B \-<number>
-causes a2p to assume that input will always have that many fields.
-.Sh "Considerations"
-A2p cannot do as good a job translating as a human would, but it usually
-does pretty well.
-There are some areas where you may want to examine the perl script produced
-and tweak it some.
-Here are some of them, in no particular order.
-.PP
-There is an awk idiom of putting int() around a string expression to force
-numeric interpretation, even though the argument is always integer anyway.
-This is generally unneeded in perl, but a2p can't tell if the argument
-is always going to be integer, so it leaves it in.
-You may wish to remove it.
-.PP
-Perl differentiates numeric comparison from string comparison.
-Awk has one operator for both that decides at run time which comparison
-to do.
-A2p does not try to do a complete job of awk emulation at this point.
-Instead it guesses which one you want.
-It's almost always right, but it can be spoofed.
-All such guesses are marked with the comment \*(L"#???\*(R".
-You should go through and check them.
-You might want to run at least once with the \-w switch to perl, which
-will warn you if you use == where you should have used eq.
-.PP
-Perl does not attempt to emulate the behavior of awk in which nonexistent
-array elements spring into existence simply by being referenced.
-If somehow you are relying on this mechanism to create null entries for
-a subsequent for...in, they won't be there in perl.
-.PP
-If a2p makes a split line that assigns to a list of variables that looks
-like (Fld1, Fld2, Fld3...) you may want
-to rerun a2p using the \-n option mentioned above.
-This will let you name the fields throughout the script.
-If it splits to an array instead, the script is probably referring to the number
-of fields somewhere.
-.PP
-The exit statement in awk doesn't necessarily exit; it goes to the END
-block if there is one.
-Awk scripts that do contortions within the END block to bypass the block under
-such circumstances can be simplified by removing the conditional
-in the END block and just exiting directly from the perl script.
-.PP
-Perl has two kinds of array, numerically-indexed and associative.
-Awk arrays are usually translated to associative arrays, but if you happen
-to know that the index is always going to be numeric you could change
-the {...} to [...].
-Iteration over an associative array is done using the keys() function, but
-iteration over a numeric array is NOT.
-You might need to modify any loop that is iterating over the array in question.
-.PP
-Awk starts by assuming OFMT has the value %.6g.
-Perl starts by assuming its equivalent, $#, to have the value %.20g.
-You'll want to set $# explicitly if you use the default value of OFMT.
-.PP
-Near the top of the line loop will be the split operation that is implicit in
-the awk script.
-There are times when you can move this down past some conditionals that
-test the entire record so that the split is not done as often.
-.PP
-For aesthetic reasons you may wish to change the array base $[ from 1 back
-to perl's default of 0, but remember to change all array subscripts AND
-all substr() and index() operations to match.
-.PP
-Cute comments that say "# Here is a workaround because awk is dumb" are passed
-through unmodified.
-.PP
-Awk scripts are often embedded in a shell script that pipes stuff into and
-out of awk.
-Often the shell script wrapper can be incorporated into the perl script, since
-perl can start up pipes into and out of itself, and can do other things that
-awk can't do by itself.
-.PP
-Scripts that refer to the special variables RSTART and RLENGTH can often
-be simplified by referring to the variables $`, $& and $', as long as they
-are within the scope of the pattern match that sets them.
-.PP
-The produced perl script may have subroutines defined to deal with awk's
-semantics regarding getline and print.
-Since a2p usually picks correctness over efficiency.
-it is almost always possible to rewrite such code to be more efficient by
-discarding the semantic sugar.
-.PP
-For efficiency, you may wish to remove the keyword from any return statement
-that is the last statement executed in a subroutine.
-A2p catches the most common case, but doesn't analyze embedded blocks for
-subtler cases.
-.PP
-ARGV[0] translates to $ARGV0, but ARGV[n] translates to $ARGV[$n].
-A loop that tries to iterate over ARGV[0] won't find it.
-.SH ENVIRONMENT
-A2p uses no environment variables.

-.SH DIAGNOSTICS
-.SH BUGS
-It would be possible to emulate awk's behavior in selecting string versus
-numeric operations at run time by inspection of the operands, but it would
-be gross and inefficient.
-Besides, a2p almost always guesses right.
-.PP
-Storage for the awk syntax tree is currently static, and can run out.

-.SH NAME
-s2p - Sed to Perl translator
-.SH SYNOPSIS
-.B s2p [options] filename
-.SH DESCRIPTION
-.I S2p
-takes a sed script specified on the command line (or from standard input)
-and produces a comparable
-.I perl
-script on the standard output.
-.Sh "Options"
-Options include:
-.TP 5
-.B \-D<number>
-sets debugging flags.
-.TP 5
-.B \-n
-specifies that this sed script was always invoked with a sed -n.
-Otherwise a switch parser is prepended to the front of the script.
-.TP 5
-.B \-p
-specifies that this sed script was never invoked with a sed -n.
-Otherwise a switch parser is prepended to the front of the script.
-.Sh "Considerations"
-The perl script produced looks very sed-ish, and there may very well be
-better ways to express what you want to do in perl.
-For instance, s2p does not make any use of the split operator, but you might
-want to.
-.PP
-The perl script you end up with may be either faster or slower than the original
-sed script.
-If you're only interested in speed you'll just have to try it both ways.
-Of course, if you want to do something sed doesn't do, you have no choice.
-It's often possible to speed up the perl script by various methods, such
-as deleting all references to $\e and chop.
-.SH ENVIRONMENT
-S2p uses no environment variables.
