NAME
ruby-build - Download, compile, and install a version of Ruby
SYNOPSIS
ruby-build [-kpv] <definition> <prefix> [-- <configure-args>...]
ruby-build {--list|--definitions}
ruby-build --version
DESCRIPTION
ruby-build downloads, compiles, and installs a Ruby version named by the definition argument into the
location specified by prefix.
The definition argument can be a path to a file on disk, in which case it is sourced into ruby-build as a
bash script.
Optionally, extra Ruby configure-args may be listed after "--" and will get forwarded to the ./configure
invocation.
By default, all compile output is redirected to a log file at $TMPDIR/ruby-build.*.log. Activate the
verbose mode to skip the log file and print everything to standard streams.
