=item Simple word matching

=item Using character classes

\d is a digit and represents [0-9], \s is a whitespace character and
represents [\ \t\r\n\f], \w is a word character (alphanumeric or _) and
represents [0-9a-zA-Z_], \D is a negated \d; it represents any character
but a digit [^0-9], \S is a negated \s; it represents any non-whitespace
character [^\s], \W is a negated \w; it represents any non-word character
[^\w], The period '.' matches any character but "\n", no modifiers (//):
Default behavior.  C<'.'> matches any character except C<"\n">.  C<^>
matches only at the beginning of the string and C<$> matches only at the
end or before a newline at the end, s modifier (//s): Treat string as a
single long line.  C<'.'> matches any character, even C<"\n">.	C<^>
matches only at the beginning of the string and C<$> matches only at the
end or before a newline at the end, m modifier (//m): Treat string as a set
of multiple lines.  C<'.'> matches any character except C<"\n">.  C<^> and
C<$> are able to match at the start or end of I<any> line within the
string, both s and m modifiers (//sm): Treat string as a single long line,
but detect multiple lines.  C<'.'> matches any character, even C<"\n">. 
C<^> and C<$>, however, are able to match at the start or end of I<any>
line within the string

=item Matching this or that

=item Grouping things and hierarchical matching

0 Start with the first letter in the string 'a', 1 Try the first
alternative in the first group 'abd', 2 Match 'a' followed by 'b'. So far
so good, 3 'd' in the regexp doesn't match 'c' in the string - a dead end. 
So backtrack two characters and pick the second alternative in the first
group 'abc', 4 Match 'a' followed by 'b' followed by 'c'.  We are on a roll
and have satisfied the first group. Set $1 to 'abc', 5 Move on to the
second group and pick the first alternative 'df', 6 Match the 'd', 7 'f' in
the regexp doesn't match 'e' in the string, so a dead end.  Backtrack one
character and pick the second alternative in the second group 'd', 8 'd'
matches. The second grouping is satisfied, so set $2 to 'd', 9 We are at
the end of the regexp, so we are done! We have matched 'abcd' out of the
string "abcde"

=item Extracting matches

=item Matching repetitions

C<a?> = match 'a' 1 or 0 times, C<a*> = match 'a' 0 or more times, i.e.,
any number of times, C<a+> = match 'a' 1 or more times, i.e., at least
once, C<a{n,m}> = match at least C<n> times, but not more than C<m> times,
C<a{n,}> = match at least C<n> or more times, C<a{n}> = match exactly C<n>
times, Principle 0: Taken as a whole, any regexp will be matched at the
earliest possible position in the string, Principle 1: In an alternation
C<a|b|c...>, the leftmost alternative that allows a match for the whole
regexp will be the one used, Principle 2: The maximal matching quantifiers
C<?>, C<*>, C<+> and C<{n,m}> will in general match as much of the string
as possible while still allowing the whole regexp to match, Principle 3: If
there are two or more elements in a regexp, the leftmost greedy quantifier,
if any, will match as much of the string as possible while still allowing
the whole regexp to match.  The next leftmost greedy quantifier, if any,
will try to match as much of the string remaining available to it as
possible, while still allowing the whole regexp to match.  And so on, until
all the regexp elements are satisfied, C<a??> = match 'a' 0 or 1 times. Try
0 first, then 1, C<a*?> = match 'a' 0 or more times, i.e., any number of
times, but as few times as possible, C<a+?> = match 'a' 1 or more times,
i.e., at least once, but as few times as possible, C<a{n,m}?> = match at
least C<n> times, not more than C<m> times, as few times as possible,
C<a{n,}?> = match at least C<n> times, but as few times as possible,
C<a{n}?> = match exactly C<n> times.  Because we match exactly C<n> times,
C<a{n}?> is equivalent to C<a{n}> and is just there for notational
consistency, Principle 3: If there are two or more elements in a regexp,
the leftmost greedy (non-greedy) quantifier, if any, will match as much
(little) of the string as possible while still allowing the whole regexp to
match.	The next leftmost greedy (non-greedy) quantifier, if any, will try
to match as much (little) of the string remaining available to it as
possible, while still allowing the whole regexp to match.  And so on, until
all the regexp elements are satisfied, 0 Start with the first letter in the
string 't', 1 The first quantifier '.*' starts out by matching the whole
string 'the cat in the hat', 2 'a' in the regexp element 'at' doesn't match
the end of the string.	Backtrack one character, 3 'a' in the regexp
element 'at' still doesn't match the last letter of the string 't', so
backtrack one more character, 4 Now we can match the 'a' and the 't', 5
Move on to the third element '.*'.  Since we are at the end of the string
and '.*' can match 0 times, assign it the empty string, 6 We are done!

=item Guidelines for Module Creation

Do similar modules already exist in some form?, Try to design the new
module to be easy to extend and reuse, Some simple style guidelines, Select
what to export, Select a name for the module, Have you got it right?,
README and other Additional Files, A description of the
module/package/extension etc, A copyright notice - see below, Prerequisites
- what else you may need to have, How to build it - possible changes to
Makefile.PL etc, How to install it, Recent changes in this release,
especially incompatibilities, Changes / enhancements you plan to make in
the future, Adding a Copyright Notice, Give the module a
version/issue/release number, How to release and distribute a module, Take
care when changing a released module

=item Guidelines for Converting Perl 4 Library Scripts into Modules

There is no requirement to convert anything, Consider the implications,
Make the most of the opportunity, The pl2pm utility will get you started,
Adds the standard Module prologue lines, Converts package specifiers from '
to ::, Converts die(...) to croak(...), Several other minor changes

=item Guidelines for Reusing Application Code

Complete applications rarely belong in the Perl Module Library, Many
applications contain some Perl code that could be reused, Break-out the
reusable code into one or more separate module files, Take the opportunity
to reconsider and redesign the interfaces, In some cases the 'application'
can then be reduced to a small

sort() has been changed to use mergesort internally as opposed to the
earlier quicksort.  For very small lists this may result in slightly slower
sorting times, but in general the speedup should be at least 20%. 
Additional bonuses are that the worst case behaviour of sort() is now
better (in computer science terms it now runs in time O(N log N), as
opposed to quicksort's Theta(N**2) worst-case run time behaviour), and that
sort() is now stable (meaning that elements with identical keys will stay
ordered as they were before the sort)

=item FAQ

1) I installed a new version of module X but CPAN keeps saying,       I
have the old version installed, 2) So why is UNINST=1 not the default?, 3)
I want to clean up my mess, and install a new perl along with	    all
modules I have. How do I go about it?, 4) When I install bundles or
multiple modules with one command	there is too much output to keep
track of, 5) I am not root, how can I install a module in a personal	  
directory?, 6) How to get a package, unwrap it, and make a change before   
   building it?, 7) I installed a Bundle and had a couple of fails. When I 
     retried, everything resolved nicely. Can this be fixed to work	 
on first try?, 8) In our intranet we have many modules for internal use.
How	  can I integrate these modules with CPAN.pm but without uploading 
     the modules to CPAN?, 9) When I run CPAN's shell, I get error msg
about line 1 to 4,	 setting meta input/output via the /etc/inputrc
file
