# ZiniGo
|
||||
|
||||
A tool written in Go for saving (legally purchased) magazines from Zinio.
|
||||
|
||||
## Usage
|
||||
./zinigo -u=Username -p=Password
|
||||
|
||||
## Requirements
|
||||
Google chrome installed, and accessible via the command `google-chrome`
|
||||
|
||||
## How it works
|
||||
ZiniGo logs into Zinio, and pulls a list of all issues purchased.
|
||||
|
||||
Each page is available as an SVG, which is then injected into n HTML page (based on template.html).
|
||||
|
||||
google-chrome is then used to print the page to PDF, and all pages are combined into a single PDF.
