A pretty system information tool written in POSIX `sh`.
|
||||
|
||||
The goal of this project is to implement a simple system
|
||||
information tool in POSIX `sh` using features built into
|
||||
the language itself (*where possible*).

The source code is highly documented and I hope it will

act as a learning resource for POSIX `sh` and simple
