+=head1 NAME
+
+Text::Restructured - Perl implementation of reStructuredText parser
+
+=head1 DOCUMENTATION
+
+The documentation is in reST format. You can build it with C<make doc>
+or visit L<http://www.prest.de/doc/>.
+
+=begin reST
+=begin Usage
+Defines for reStructuredText parser
+-----------------------------------
+-D align=<0|1> Allow inferring right/center alignment in
+ single line simple table cells (default is 1).
+-D entry-attr=<text>
+ Specifies attributes to be passed to table entry
+ (default is ''). Note: this option can be
+ changed on the fly within a table by using a perl
+ directive to set $main::opt_D{entry_attr}.
+-D file-insertion-enabled[=<0|1>]
+ Allows include directives to include files, which may
+ be a potential security hole. Default is 1.
+-D ignore-include-errs[=<0|1>]
+ Specifies that no error should be generated for
+ missing include files. Default is 0.
+-D image-exts=<ext-list>
+ A comma-separated list of "ext1=ext2" pairs where
+ any URI with extension ext1 has it mapped to ext2.
+ This option allows using a single document
+ source with multiple writers by using whatever
+ figure extension is appropriate for a given writer.
+-D include-ext=<text>
+ A colon-separated list of extensions to check for
+ included files. Default is ":.rst:.txt".
+-D include-path=<text>
+ A colon-separated list of directories for the
+ include directive to search. The special token
+ "<.>" represents the directory of the file
+ containing the directive (which may not be the
+ same as the directory in which trip is invoked, ".".
+ Default is "<.>".
+-D mstyle=<comma-separated-attr-val-list>
+ A comma-separated set of attribute=value pairs to
+ be used for the <mstyle> elements of MathML
+ markup. Default is displaystyle=true for
+ ascii-mathml directive.
+-D nest-inline[=<0|1>]
+ Specify whether to allow nesting of inline markup.
+ There are some limitations, like strong cannot be
+ nested within emphasis.
+ Default is 1 (1 if specified with no value).
+-D perl-path=<text>
+ A colon-separated list of directories to search
+ for Perl modules. The special token "<INC>"
+ represents the default Perl include path.
+ Default is "<INC>".
+-D raw-enabled[=<0|1>]
+ Allows raw directives to be processed, which may
+ be a potential security hole. Default is 1.
+-D report=<level> Set verbosity threshold; report system messages
+ at or higher than <level> (by name or number:
+ "info" or "1", warning/2, error/3, severe/4;
+ also, "none" or 5). Default is 2 (warning).
+-D row-attr=<text>
+ Specifies attributes to be passed to table rows
+ (default is ''). Note: this option can be
+ changed on the fly within a table by using a perl
+ directive to set $main::opt_D{row_attr}.
+-D source=<text> Overrides the file name as the source.
+-D table-attr=<text>
+ Specifies attributes to be passed to tables (default
+ is '${Text::Restructured::DEFAULTS{table_attr}}').
+ Note: this option can be changed on the fly to
+ have tables with different characteristics by
+ using a perl directive to set
+ $main::opt_D{table_attr}.
+-D tabstops=<num> Specifies that tab characters are assumed to tab
+ out to every <num> characters (default is 8).
+-D xformoff=<regexp>
+ Turns off default transforms matching regexp.
+ (Used for internal testing.)

+# Many static (read-only) variables defined in BEGIN blocks (not documented).
+
+# Data structures:
+# _`Text::Restructured`: reStructuredText _`parser` hash reference with
+# the following keys:
+# ``next_id``: The next id to be returned by Id() method;
+# ``SEC_LEVEL``: Hash reference whose keys are header styles and whose
+# value (if defined) indicates the level of
+# sections encoded with that header style.
+# ``SEC_DOM``: Array reference whose index is the section level and
+# whose value is the section DOM object at that level.
+# ``SEC_STYLE``: Array reference whose index is the section level and
+# whose value is the section style at that level.
+# ``ANONYMOUS_TARGETS``: Array reference of references to anonymous
+# target DOMs in file order.
+# ``REFERENCE_DOM``: Hash reference whose keys are tags and whose values
+# are references to a hash with names or ids as
+# keys and the associated target DOM object as
+# value.
+# ``TARGET_NAME``: Hash reference whose keys are namespace ids and whose
+# values are references to a hash whose keys
+# are names and whose value is a reference to
+# an array of all the DOM objects having that
+# name in that name space.
+# ``ALL_TARGET_IDS``: Hash reference whose keys are ids and whose value
+# is a reference to an array of all the DOM
+# objects having that id.
+# ``ALL_TARGET_NAMES``: Hash reference whose keys are names and whose
+# value is a reference to an array of all the
+# DOM objects having that name.
+# ``MY_ROLES``: Hash reference whose keys are the role names that are
+# currently defined for the current document
+# (it gets reset between documents) and whose
+# values are Role definition hash references.
+# ``MY_DEFAULT_ROLE``: The current name of the default role
+# for the current document. Initially
