* The aim of this program is to compare two builds of the Linux kernel and
* list all the ABI differences in the given list of symbols between these two
* builds.
*
* For both builds the kabi information first needs to be stored in a text
* files, see generate(). The the two dumps can be compared, see compare().
* The format of the kabi information loosely follow the syntax of the Go
* programming language for its ease of parsing.
