# This script installs micro.

# This script will install micro to your user bin directory ~/.local/bin
# (I don't use ''~/bin' because it muddies up 'ls')

  #{Paint['NOTE','orange']}: Termux, while being the only linux subsystem
  for android that micro_install supports, is a bit wonky when it
  comes to shebangs and Bash startup.
    
  1. If you haven't already, create a '.bashrc' in '~'
  2. Add the next line into your bashrc after everything else
     having to do with paths.

     export PATH="#{Dir.home}/.local/bin:$PATH"

  3. Restart your bash session, or re-source your .bashrc
  
      'source ~/.bashrc'
