With all the good changes to lemon recently, I thought I'd post changes that I
have made to my personal copy. One of my customers requires that I demonstrate
the version of all build tools I use at build time, so I added a few command
line parameters to help with that.
It would be nice if the version identifier for lemon would increment as it
matures, but I understand why it doesn't currently increment. It doesn't make
sense to tie the version of lemon.exe to sqlite3.exe. I've toyed with using
the build script to query fossil finfo lemon.c --limit 1 and use the artifact
id or version id to uniquely identify a particular lemon build.
