NAME
    Config::Dot - Module for simple configure file parsing.

SYNOPSIS
     my $cnf = Config::Dot->new(%params);
     my $struct_hr = $cnf->parse($string);
     $cnf->reset;
     my $serialized = $cnf->serialize;

METHODS
    "new(%params)"
             Constructor.

            *       "callback"

                     Callback code for adding parameter.
                     Callback arguments are:
                     $key_ar - Reference to array with keys.
                     $value - Key value.
                     Default is undef.

            *       "config"

                     Reference to hash structure with default config data.
                     This is hash of hashes structure.
                     Default value is reference to blank hash.

            *       "set_conflicts"

                     Set conflicts detection as error.
                     Default value is 1.

    "parse($string_or_array_ref)"
             Parse string $string_or_array_ref or reference to array $string_or_array_ref.
             Use $INPUT_RECORD_SEPARATOR variable to split lines.
             Returns hash structure with configuration.

    "reset()"
             Reset content in class (config parameter).
             Returns undef.

    "serialize()"
             Serialize 'config' hash to output.
             Use $INPUT_RECORD_SEPARATOR variable to join lines.
             Returns string with serialized configuration.

PARAMETER_FILE
     # Comment.
     # blabla

     # White space.
     /^\s*$/

     # Parameters.
     # Key must be '[-\w\.:,]+'.
     # Separator is '='.
     key=val
     key2.subkey.subkey=val

ERRORS
     new():
             Bad 'config' parameter.
             Parameter 'callback' isn't code reference.
             From Class::Utils::set_params():
                     Unknown parameter '%s'.

     parse():
             Bad key '%s' in string '%s' at line '%s'.
             From Config::Utils::hash():
                      Conflict in '%s'.

     serialize():
             Unsupported stay with newline in value.
