-=head1 NAME
-
-Config::Grammar - A grammar-based, user-friendly config parser
-
-=head1 SYNOPSIS
-
- use Config::Grammar;
-
- my $parser = Config::Grammar->new(\%grammar);
- my $cfg = $parser->parse('app.cfg') or die "ERROR: $parser->{err}\n";
- my $pod = $parser->makepod();
- my $ex = $parser->maketmpl('TOP','SubNode');
- my $minex = $parser->maketmplmin('TOP','SubNode');
-
-=head1 DESCRIPTION
-
-Config::Grammar is a module to parse configuration files. The
-configuration may consist of multiple-level sections with assignments
-and tabular data. The parsed data will be returned as a hash
-containing the whole configuration. Config::Grammar uses a grammar
-that is supplied upon creation of a Config::Grammar object to parse
-the configuration file and return helpful error messages in case of
-syntax errors. Using the B<makepod> method you can generate
-documentation of the configuration file format.
-
-The B<maketmpl> method can generate a template configuration file. If
-your grammar contains regexp matches, the template will not be all
-that helpful as Config::Grammar is not smart enough to give you sensible
-template data based in regular expressions. The related function
-B<maketmplmin> generates a minimal configuration template without
-examples, regexps or comments and thus allows an experienced user to
-fill in the configuration data more efficiently.
-
-
-=head2 Grammar Definition
-
-The grammar is a multiple-level hash of hashes, which follows the structure of
-the configuration. Each section or variable is represented by a hash with the
-same structure. Each hash contains special keys starting with an underscore
-such as '_sections', '_vars', '_sub' or '_re' to denote meta data with information
-about that section or variable. Other keys are used to structure the hash
-according to the same nesting structure of the configuration itself. The
-starting hash given as parameter to 'new' contains the "root section".
-
-=head3 Special Section Keys
-
-=over 12
-
-=item _sections
-
-Array containing the list of sub-sections of this section. Each sub-section
-must then be represented by a sub-hash in this hash with the same name of the
-sub-section.
-
-The sub-section can also be a regular expression denoted by the syntax '/re/',
-where re is the regular-expression. In case a regular expression is used, a
-sub-hash named with the same '/re/' must be included in this hash.
-
-=item _vars
-
-Array containing the list of variables (assignments) in this section.
-Analogous to sections, regular expressions can be used.
-
-=item _mandatory
-
-Array containing the list of mandatory sections and variables.
-
-=item _inherited
-
-Array containing the list of the variables that should be assigned the
-same value as in the parent section if nothing is specified here.
-
-=item _table
-
-Hash containing the table grammar (see Special Table Keys). If not specified,
-no table is allowed in this section. The grammar of the columns if specified
-by sub-hashes named with the column number.
-
-=item _text
-
-Section contains free-form text. Only sections and @includes statements will
-be interpreted, the rest will be added in the returned hash under '_text' as
-string.
-
-B<_text> is a hash reference which can contain a B<_re> and a B<_re_error> key
-which will be used to scrutanize the text ... if the hash is empty, all text
-will be accepted.
-
-=item _order
-
-If defined, a '_order' element will be put in every hash containing the
-sections with a number that determines the order in which the sections were
-defined.
-
-=item _doc
-
-Describes what this section is about
-
-=item _sub
-
-A function pointer. It is called for every instance of this section,
-with the real name of the section passed as its first argument. This is
-probably only useful for the regexp sections. If the function returns
-a defined value it is assumed that the test was not successful and an
-error is generated with the returned string as content.
-
-=back
-
-=head3 Special Variable Keys
-
-=over 12
-
-=item _re
-
-Regular expression upon which the value will be checked.
-
-=item _re_error
-
-String containing the returned error in case the regular expression doesn't
-match (if not specified, a generic 'syntax error' message will be returned).
-
-=item _sub
-
-A function pointer. It called for every value, with the value passed as its
-first argument. If the function returns a defined value it is assumed that
-the test was not successful and an error is generated with the returned
-string as content.
-
-If the '_varlist' key (see above) is defined in this section, the '_sub'
-function will also receive an array reference as the second argument. The
-array contains a list of those variables already defined in the same
-section. This can be used to enforce the order of the variables.
-
-=item _default
-
-A default value that will be assigned to the variable if none is specified or inherited.
-
-=item _doc
-
-Description of the variable.
-
-=item _example
-
-A one line example for the content of this variable.
-
-=back
-
-=head3 Special Table Keys
-
-=over 12
-
-=item _columns
-
-Number of columns. If not specified, it will not be enforced.
-
-=item _key
-
-If defined, the specified column number will be used as key in a hash in the
-returned hash. If not defined, the returned hash will contain a '_table'
-element with the contents of the table as array. The rows of the tables are
-stored as arrays.
-
-=item _sub
-
-they work analog to the description in the previous section.
-
-=item _doc
-
-describes the content of the column.
-
-=item _example
-
-example for the content of this column
-
-=back
-
-=head3 Special Text Keys
-
-=over 12
-
-=item _re
-
-Regular expression upon which the text will be checked (everything as a single
-line).
-
-=item _re_error
-
-String containing the returned error in case the regular expression doesn't
-match (if not specified, a generic 'syntax error' message will be returned).
-
-=item _sub
-
-they work analog to the description in the previous section.
-
-=item _doc
-
-Ditto.
-
-=item _example
-
-Potential multi line example for the content of this text section

-
-=head2 Configuration Syntax
-
-=head3 General Syntax
-
-'#' denotes a comment up to the end-of-line, empty lines are allowed and space
-at the beginning and end of lines is trimmed.
-
-'\' at the end of the line marks a continued line on the next line. A single
-space will be inserted between the concatenated lines.
-
-'@include filename' is used to include another file. Include works relative to the
-directory where the parent file is in.
-
-'@define a some value' will replace all occurences of 'a' in the following text
-with 'some value'.
-
-Fields in tables that contain white space can be enclosed in either C<'> or C<">.
-Whitespace can also be escaped with C<\>. Quotes inside quotes are allowed but must
-be escaped with a backslash as well.
-
-=head3 Sections
-
-Config::Grammar supports hierarchical configurations through sections, whose
-syntax is as follows:
-
-=over 15
-
-=item Level 1
-
-*** section name ***
-
-=item Level 2
-
-+ section name
-
-=item Level 3
-
-++ section name
-
-=item Level n, n>1
-
-+..+ section name (number of '+' determines level)
-
-=back
-
-=head3 Assignments
-
-Assignements take the form: 'variable = value', where value can be any string
-(can contain whitespaces and special characters). The spaces before and after
-the equal sign are optional.
-
-=head3 Tabular Data
-
-The data is interpreted as one or more columns separated by spaces.
-

-=head1 NAME
-
-Config::Grammar::Dynamic - A grammar-based, user-friendly config parser
-
-=head1 DESCRIPTION
-
-Config::Grammar::Dynamic is like Config::Grammar but with some additional
-features useful for building configuration grammars that are dynamic, i.e.
-where the syntax changes according to configuration entries in the same file.
-
-The following keys can be additionally specified in the grammar when using this
-module:
-
-=head2 Special Section Keys
-
-=over 12
-
-=item _dyn
-
-A subroutine reference (function pointer) that will be called when
-a new section of this syntax is encountered. The subroutine will get
-three arguments: the syntax of the section name (string or regexp), the
-actual name encountered (this will be the same as the first argument for
-non-regexp sections) and a reference to the grammar tree of the section.
-This subroutine can then modify the grammar tree dynamically.
-
-=item _dyndoc
-
-A hash reference that lists interesting names for the section that
-should be documented. The keys of the hash are the names and the
-values in the hash are strings that can contain an explanation
-for the name. The _dyn() subroutine is then called for each of
-these names and the differences of the resulting grammar and
-the original one are documented. This module can currently document
-differences in the _vars list, listing new variables and removed
-ones, and differences in the _sections list, listing the
-new and removed sections.
-
-=item _recursive
-
-Array containing the list of those sub-sections that are I<recursive>, ie.
-that can contain a new sub-section with the same syntax as themselves.
-
-The same effect can be accomplished with circular references in the
-grammar tree or a suitable B<_dyn> section subroutine (see below},
-so this facility is included just for convenience.
-
-=back
-
-=head2 Special Variable Keys
-
-=over 12
-
-=item _dyn
-
-A subroutine reference (function pointer) that will be called when the
-variable is assigned some value in the config file. The subroutine will
-get three arguments: the name of the variable, the value assigned and
-a reference to the grammar tree of this section. This subroutine can
-then modify the grammar tree dynamically.
-
-Note that no _dyn() call is made for default and inherited values of
-the variable.
-
-=item _dyndoc
-
-A hash reference that lists interesting values for the variable that
-should be documented. The keys of the hash are the values and the
-values in the hash are strings that can contain an explanation
-for the value. The _dyn() subroutine is then called for each of
-these values and the differences of the resulting grammar and
-the original one are documented. This module can currently document
-differences in the _vars list, listing new variables and removed
-ones, and differences in the _sections list, listing the
-new and removed sections.

-
-=head1 DESCRIPTION
-
-HMAC is used for message integrity checks between two parties that
-share a secret key, and works in combination with some other Digest
-algorithm, usually MD5 or SHA-1. The HMAC mechanism is described in
-RFC 2104.
-
-HMAC follow the common C<Digest::> interface, but the constructor
-takes the secret key and the name of some other simple C<Digest::>
-as argument.
