## What it is
An Android custom View library that draws coupon-style backgrounds with semicircle notches and dashed borders, fully customizable via XML attributes or code. It also provides a helper class to add the same notched background to other View subclasses.

## Use cases
- draw coupon ticket UI with notched edges in an Android app
- add dashed borders to a view without image assets
- create punch-hole semicircle edges on a card layout
- build promotional voucher screens in Android
- apply sawtooth background effects to LinearLayout or TextView
- customize dash line color, gap, and margins per side

## When to choose
- you need coupon/ticket visuals on Android without PNG backgrounds
- you want per-side control of notches and dashed lines via XML attributes
- you want to reuse the effect on custom View subclasses via the helper

## When to avoid
- you need coupon UI on iOS, web, or non-Android platforms
- you need complex animated or interactive coupon effects beyond static drawing
- you need a maintained library with recent updates (last release 2017)
