Exercise 1: What LLDB Is — Possible Solution
=============================================

TASK
Explain what LLDB is, who created it, and what it replaced in Xcode. Then
say what evidence suggests LLDB skills are not limited to Xcode.

ANSWER
LLDB is a debugger created by Chris Lattner as part of the LLVM project. It
became the default debugger for Xcode 5 and later, replacing GDB.

EVIDENCE IT IS NOT LIMITED TO XCODE
The reference article says LLDB runs on macOS, Linux, FreeBSD, NetBSD and
Windows, and that it is also used in Android Studio and Visual Studio Code,
among other tools. A skill learned with LLDB commands therefore has uses
outside Xcode.

CAUTION
The article does not say how similar each tool's console is, so I would not
claim the commands behave identically everywhere without trying them.
