Bubblegum is a daemon written in C which watches a file's access, modification and inode change times, and MD5 checksums. It can run a command with info expansions, read files from a filelist, log to a file or syslogd, and more.
Bubblegum is a type of chewing gum that is especially designed for blowing bubbles. It is often pink in color and has a particular flavor. Bubble gum tends to be more viscous than standard chewing gum in order to facilitate bubble blowing.
