.SH "DESCRIPTION"
.sp
\fBruby\-build\fP provides a simple way to compile and install different
versions of Ruby on UNIX\-like systems.
.sp
ruby\-build downloads, builds and installs the Ruby version specified
in a \fIDEFINITION\fP into a \fIPREFIX\fP directory. Definitions can be chosen
from the list of installed definitions or by specifying a file path
for a definition.
.sp
rbenv(1) users can also use the provided \fBrbenv install\fP
command, which installs Rubies into the \f[CR]rbenv\fP directory.
