texinfo

### Note: at the time of writting, texinfo depends on older perl5
### I downgrade to previous version (5.28.0)
### loadable library and perl binaries are mismatched (got handshake key 0xce00080, needed 0xed00080)

Commands:
# setup miktex first
# if you don't want to keep miktex in it latter on
# backup your mydata.tgz with a different name
# Note that if you're running miktex for the first time
# due to a bug that had yet to be fixed
# you have to load it in copy mode
#   tce-load -ci miktex
# then open miktex-console in GUI
# choose the install mode
# It's recommended to install locally
# test run R configure in a GUI terminal
# a dialog would popup, install those missing packages
# backup with filetool then reboot
# now the miktex extension can be loaded normally
