+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

+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
