for the installation of ConTeXt, when the shell script `install.sh` start to run, any way to show the downloading progress when it fetches the zip from the site? For example: ``` mtx-install | fetching 'http://lmtx.pragma-ade.com/install-lmtx//texmf.zip' ``` It looks stopped while the downloading is going on. but the user may wrongly regard something goes wrong When the networking speed is slow. Two options would be nice: a) just how the current percentage of the downloaded data; b) even better, under the line, starting a new line, starting with a percentage, then followed by dash characters plus an arrow like `->` to show the downloading progress dynamically --- while the downloaded data adding up, the number of dash characters prolongs accordingly.
