Replying to [comment:9 jhpalmieri]:
> When getting the info on-line, the "`| cat`" in `sage-download-file
"$PKG_URL" | cat` should not be necessary, but without it, the file is
dumped to standard output in the middle of some brackets printed by sage-
download-file. Should I instead do `sage-download-file "$PKG_URL" 2>
/dev/null`? I don't want to lose important error messages.
The `| cat` is a silly hack which just happens to work because of I/O
buffers. I would redirect `2>/dev/null`. For `./sage --info`, I don't
want to rely anyway on the existence of those `.txt` files. In case
downloading the txt file fails (and we don't see the error message),
simply fall back to the old method of downloading the spkg and extracting
`SPKG.txt`.
