NAME
savevars - Perl pragma to auto-load and save global variables
SYNOPSIS
use savevars qw($frob @mung %seen);
DESCRIPTION
This module will, like use vars
, predeclare the variables in the list. In addition, the listed variables are retrieved from a per-script configuration file and the values are stored on program end. The filename of the configuration file is "$ENV{HOME}/.${progname}rc", where progname is the name of the current script.
The values are stored using the Data::Dumper module, which is already installed with perl5.005 and better.
FUNCTIONS
cfgfile
Return the pathname of the current configuration file.
writecfg
Write the variables to the configuration file. This method is called at END.
dont_write_cfgfile
If this function is called, then the configuration file will not be written at END.
