## Configuring Asym and PASS2
##
## Asym will read a configuration file, if supplied, to configure the CPU
## model, memory, and caches.  The configuration file is read once, when
## Asym or PASS2 first initializes.
##
## Locating the Configuration File
##
## Asym will search for the configuration file in the following places:
##
##  1) In the file named in the environment variable ASYM_CONFIG.
##
##  2) In the current directory file .asym_config.
##
##  3) In the home directory file .asym_config, if the HOME
##     environment variable is set.
##
## For example, if you have a configuration file you commonly use, you
## might place the following in your .login file (assuming sh or bash):
##
##  ASYM_CONFIG=/usr/local/share/asym.cfg
##  export ASYM_CONFIG
##
## or Windows environment:
##
##  set ASYM_CONFIG=C:\USER\ASYM.CFG
##
## Configuration File Organization
##
## The configuration file consists of a series of commands which specify
## different characteristics of Asym.  Each command starts with a command
## word and is followed by a series of one or more attributes, which may
## be specified in any order.  An attribute may require a string or
## numeric value.  Strings are sequences of letters and numbers, without
## spaces.  Numbers may be specified in decimal (the default) or in hex
## by preceding the number with 0x.  Numbers may also have a "K" or "k"
## suffix, which means to multiply the number by 1024.
##
## For example,
##
##  CPU     model=5280
##
## The command word is CPU and there is one attribute, model, which
## specifies a numeric value, 5280.
##
## Command words and attributes may be in either case, or mixed.  For the
## previous example, Model or MODEL, or even MoDeL would have been
## equivalent.  Command words and attributes may be abbreviated, so long
## as the abreviation cannot be confused with other command words or
## attributes. They must be separated by one or more blanks or tabs and
## blanks may be inserted before or after the equal sign.  Anything on a
## line following a pound sign (#) will be considered a comment.  A
## command may be continued onto the next line by having a backslash (\)
## as the last non-blank character.
##
## For example,
##
##  CPU         # specify CPU           \
##      model = 5280
##
## This would be the same as previous example.
