* Section 2 - Input Description *

*********************************
This section of the manual describes the input to
GAMESS. The section is written in a reference, rather than
tutorial fashion. However, there are frequent reminders
that more information can be found on a particular input
group, or type of calculation, in the 'Further Information'
section of this manual. Numerous complete input files are
shown in the 'Input Examples' section.
Note that this chapter of the manual can be searched
online by means of the "gmshelp" command, if your computer
runs Unix. A command such as
gmshelp scf
will display the $SCF input group. With no arguments, the
gmshelp command will show you all of the input group names.
Type "" to see the next screen, "b" to back up to
the previous screen, and "q" to exit the pager. If gmshelp
does not work, ask the person who installed GAMESS to fix
the 'gmshelp' script, as it is extremely useful.
The order of this section is chosen to approximate the
order in which most people prepare their input ($CONTRL,
$BASIS/$DATA, $GUESS, and so on). The next few pages
contain a list of all possible input groups, grouped in
this way. The PDF version of this file contains an index
of all group names in alphabetical order.
