If you are nerdy/awesome enough to be into (1) the pedagogy of Irish traditional woodwind playing and (2) open-source text-based music notation software, then you may want to check out my set of symbols for Lilypond, based on the excellent ornamentation system by Grey Larsen. You can get the .ily file on GitHub (and submit your pull requests to make improvements to my code).
If you are unfamiliar with Mr. Larsen’s system and you play pennywhistles or wooden flutes, then really I must insist that you buy a copy of his The Essential Guide to Irish Flute and Tin Whistle immediately—his ornamentation system is clear and logical and should be regarded as the standard for teaching and learning Irish-traditional ornamentation for wind instruments.
If you are unfamiliar with Lilypond, chances are good that you won’t like it even though it’s free and produces much better notation than the software you already spent several hundred dollars on.
Also, it’s worth noting that Chris Throup already had a similar idea a few years ago. Mine is a bit more complete, but his is really simple.
