## Overview

This Go command-line calculator accepts a vendor/action and device identifiers, dispatches to vendor-specific unlock algorithms, and prints JSON-encoded results. Its branches cover BlackBerry MEP/PRD lookup and codes, older Huawei USB modem codes, three ZTE variants, and Alcatel C700-family codes. The BlackBerry lookup tables are a substantial internal data layer. Relationships are grounded in the shown main dispatch and function calls; README statements preserve documented capabilities where implementation details are not shown.

Main entry points: [`main.go`](https://github.com/alexanderritola/go-unlock-code-calculator/blob/master/main.go) (Command dispatch), [`Blackberry.go`](https://github.com/alexanderritola/go-unlock-code-calculator/blob/master/Blackberry.go) (MEP and PRD codes), [`findMEP.go`](https://github.com/alexanderritola/go-unlock-code-calculator/blob/master/findMEP.go) (MEP and PRD tables), [`Huawei.go`](https://github.com/alexanderritola/go-unlock-code-calculator/blob/master/Huawei.go) (Old modem codes)
