Megav2Backenda� Backend for MEGA.nz cloud storage, only one that works for accounts created since Nov. 2018
See https://github.com/megous/megatools/issues/411 for more details
This MEGA backend resorts to official tools (MEGAcmd) as available at https://mega.nz/cmd
MEGAcmd works through a single binary called "mega-cmd", which talks to a backend server
"mega-cmd-server", which keeps state (for example, persisting a session). Multiple "mega-*"
shell wrappers (ie. "mega-ls") exist as the user interface to "mega-cmd" and MEGA API
The full MEGAcmd User Guide can be found in the software's GitHub page below :
