+This module is the beginning of a set of tools for dealing with ABC music
+files in Perl 6.
+
+The most useful standalone tool here is the abc2ly script, which converts ABC
+files to Lilypond format, allowing you to create beautiful PDF sheet music.

+    env PERL6LIB=/Users/colomon/tools/ABC/lib: perl6 bin/abc2ly.pl <frip.abc >frip.ly

+As of 11/29/2011, this works on the latest Rakudo nom, and on the old 7/11 Rakudo Star.

Subject: [PATCH 229/389] Replace method for statement with flatmap

The `for` method has been deprecated in favour of `flatmap`.  The old syntax
will be removed in Rakudo version 2015.09; this change removes the
deprecation warning emitted from the current version of Rakudo.

Subject: [PATCH 230/389] Update tests now that non-matching regexps return Nil

Previously (before 2013.05) Rakudo returned the empty string from regexps
which didn't match. From Rakudo 2013.05 onwards, regexps not matching a
value return Nil, thus this change updates the test suite accordingly, and
these tests now pass with the current Rakudo.

Subject: [PATCH 231/389] Flatten zip operator output explicitly

The output of the zip operator `Z` used to be flattened implicitly.  This is
no longer the case, thus to reinstate the previous behaviour expected in the
context tests, the zipped lists need to be explicitly flattened before their
values are passed into the relevant for loop.  This change makes the
`context.t` tests pass.

Subject: [PATCH 262/389] Add mandatory "perl" META field

The `perl` field specifies the minimal perl version for which this distribution can be installed and is a mandatory field. The value of `"6.*"` indicates any version suffices.

It is recommended to use [Test::META](https://modules.perl6.org/repo/Test::META) module as an author test, to catch any issues with the META file.

Since these bar numbers are currently very wrong, not showing them

Subject: [PATCH 278/389] Use modern META filename

The `META.info` is a legacy, pre-Christmas name. While it's still currently supported,
`META6.json` is the new name. And since a lot of people simply copy some module's
structure, the old name still proliferates, so we're trying to get rid of it for good
by sending PRs to any modules that use the old name, to switch to the modern name.

of a tune, which in turn means we don't generate
\break \noPageBreak at the end of every tune.

+# ABC
+
+This module is a set of tools for dealing with [ABC music notation](https://abcnotation.com/wiki/abc:standard:v2.1) files in Raku (formerly known as Perl 6).  This includes a grammar for most of the notation format (the standard has a lot of twisty corners, and we do not support all of them), Raku data structures for representing them, and some useful utilities.
+
+```raku
+my $music = q:to<ABC-end>;
+    X:044
+    T:Elsie Marley
+    B:Robin Williamson, "Fiddle Tunes" (New York 1976)
+    N:"printed by Robert Petrie in 1796 and is
+    N:"described by him as a 'bumpkin'."
+    Z:Nigel Gatherer
+    M:6/8
+    L:1/8
+    K:G
+    BAB G2G|G2g gdc|BAB G2G|=F2f fcA|
+    BAB G2G|G2g gdB|c2a B2g|A2=f fcA:|
+    ABC-end
+
+my $match = ABC::Grammar.parse($music, :rule<tune>, :actions(ABC::Actions.new));
+ok $match, 'tune recognized';
+isa-ok $match.ast, ABC::Tune, 'and ABC::Tune created';
+ok $match.ast.header.is-valid, "ABC::Tune's header is valid";
+is $match.ast.music.elems, 57, '$match.ast.music has 57 elements';
+```
+
+There are several scripts in bin/ built on the library:
+
+* abc2ly: converts an ABC file to the Lilypond ly format, then invokes Lilypond on it to create high quality sheet music.  If you install ABC using zef you should just be able to say ```abc2ly wedding.abc```to convert ```wedding.abc``` to ```wedding.pdf``` via Lilypond file ```wedding.ly```
+
+    NOTE: Lilypond also has an abc2ly script; last time I tried it it produced
+    hideous looking output from Lilypond.  If you've got both installed, you will
+    have to make sure the Raku bin of abc2ly appears first in your PATH.
+
+* abc2book: Given an ABC file and a simple “book” instructions file (our own format), this makes a book PDF.  This uses Lilypond for music formatting, LaTeX for table of contents and index of tunes, and qpdf to stitch the results together into one file.  This is still pretty experimental, but has produced one published book, [The Fiddle Music of Newfoundland & Labrador Volume 1, Revised 2020 Edition](https://fmnl1.nltrad.ca)
+
+* abctranspose: Simple tool for transposing ABC files.
+
+* abcoctave: Simple tool for shifting the octave of ABC files.
