# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

$NAME: $NAME (Fortran support for GCC)
$NAME: This package contains those parts of the compiler collection needed
$NAME: to compile Fortran code. The base gcc package is also required.
$NAME: Its primary base is the ANSI FORTRAN 95 standard, with some
$NAME: extensions popularized by the 'f77' and 'f2c' compilers, other
$NAME: compilers (such as Digital products), and the Fortran 90 standard.
