1628 Installation directories:
1629 --prefix=PREFIX install architecture-independent files in PREFIX
1630 [$ac_default_prefix]
1631 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1632 [PREFIX]
1633
1634 By default, \`make install' will install all the files in
1635 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1636 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1637 for instance \`--prefix=\$HOME'.
