To install Yaf77:

1)  If you have already some version of f77 script, save it under another
    name, e.g. f77.orig

2)  Copy f77 from this directory to any place on your searching path, for
    example, to /usr/bin

3a) If your box is Linux with aout compiler&tools, copy libF77ext_aout.a
    to /usr/lib as libF77ext.a
3b) If you have a Linux ELF distribution installed, copy libF77ext_elf.a
    to /usr/lib as libF77ext.a; if you still want to produce (sometimes)
    aout format binaries, copy libF77ext_aout.a to /usr/i486-linuxaout/lib
    as libF77ext.a, too
3c) If you computer is not Intel's with Linux OS, go to F77ext dir and issue
    `make'. You should get libF77ext.a, which is to be copied to /usr/lib

That's all. Enjoy!
