NAME
     pcp.conf - the Performance Co-Pilot configuration and environment file

SYNOPSIS
     /etc/pcp.conf

DESCRIPTION
     When using Performance Co-Pilot (PCP) tools and utilities and when
     calling PCP library functions, a standard set of environment variables
     are defined in /etc/pcp.conf.  These variables are generally used to
     specify the location of various PCP pieces in the file system and may be
     loaded into shell scripts by sourcing the /etc/pcp.env(4) shell script
     and queried by C/C++ programs using the __pmGetConfig(3) library
     function.  If a variable is already defined in the environment, the
     values in pcp.conf do not override those values, i.e. the values in
     pcp.conf serve as installation defaults only.

     Both the pcp.env and pcp.conf files are expected to be found in /etc by
     default.  If required, the pcp.conf file may be relocated and PCP_CONF
     set in the environment to specify the full path to the new location.  The
     pcp.env file can not be relocated (this is the only hard coded path
     required by PCP).

     The syntax rules for pcp.conf are as follows :

     1.  the general syntax is
                 PCP_VARIABLE_NAME=variable value to end of line

     2.  lines that begin with # and all blank lines are ignored.

     3.  all variables must be prefixed with PCP_.  This is a security issue -
         variables that do not have this prefix will be silently ignored.

     4.  there should be no space between the variable name and the literal =
         and no space between the = and the variable value (unless the value
         actually starts with a space).  This is required because the pcp.conf
         file may be sourced directly by Makefiles as well as interpreted by
         the pcp.env script and the __pmGetConfig function.

     5.  variable values may contain spaces and should not be quoted.  The
         pcp.env script automatically quotes all variable values from the
         character immediately following the = through to the end of the line.

     For further details and an explanation of the use of each variable, see
     the comments in the /etc/pcp.conf file itself.

ENVIRONMENT
     The PCP_CONF environment variable specifies an alternative path to the
     pcp.conf file.
