| # pandoc to do the conversion. | |
| # | |
| # 1. Install pandoc from http://johnmacfarlane.net/pandoc/ | |
| # 2. Copy this script into the directory containing the .md files | |
| # 3. Ensure that the script has execute permissions | |
| # 4. Run the script | |

You might want to read this to get an introduction to armel vs armhf.
If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.
First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux
The goal of this is to have an easily-scannable reference for the most common syntax idioms in JavaScript and Rust so that programmers most comfortable with JavaScript can quickly get through the syntax differences and feel like they could read and write basic Rust programs.
What do you think? Does this meet its goal? If not, why not?
