Apply shell for Exo - Create stack for build projects (exobuild). - Create alias for quick run command. - Create function for run sequential other command. - Setup or install other application help for work in eXo - Create function for automatically run some stack (ex: jenkins) - Create function (search by rules) for checking bug in code. - Maybe we can use find/grep/sed for fix some bug :D. (ex: accessibility )
