# A word about this shell script: | |
# | |
# It must work everywhere, including on systems that lack | |
# a /bin/bash, map 'sh' to ksh, ksh97, bash, ash, or zsh, | |
# and potentially have either a posix shell or bourne | |
# shell living at /bin/sh. | |
# | |
# See this helpful document on writing portable shell scripts: | |
# http://www.gnu.org/s/hello/manual/autoconf/Portable-Shell.html | |
# | |
# The only shell it won't ever work on is cmd.exe. | |

# on some systems, you can just do cat>npm-install.sh | |
# which is a bit cuter. But on others, &1 is already closed, | |
# so catting to another script file won't do anything. | |
# Follow Location: headers, and fail on errors | |
