This spec utilizes a handy method of manual version control (a.k.a. versioning). Versioning is used so you don't have to erase, delete, or otherwise forget what you did. This also helps you to see your iterations (changes and revisions) as improvements (enhancements) or dead-ends (rejects).
Today's date in MMDDYY format at the end of your file name (before your extension).
MM = Month as two numbers (02 for February)
DD = Day as two numbers (03 for the third day)
YY = Year as last two numbers of year (27 for 2027)
b = letters b-z to allow for multiple versions within the same day.
