NAME
        AnyData::Storage::File -- manipulate files with rich warnings

DESCRIPTION
        Opens, reads from, writes to, creates and destroys files with numerous
        options for error handling, flocking, binmode, etc.

        The simplest form is the equivalent of

              my $f    = AnyData::Storage::File->new(dirs=>\@dirs,flock=>1);
              my $str1 = $f->adSlurp($file);


              for( @dirs ) {
                  open(IN,$file) or die $!;
              }
              sub slurp {
                  local *IN;
                  local $/ = undef;
              }

        But, depending on how you set the default behaviour

SYNOPSIS
        use AnyData;
        my $f = AnyData::Storage::File->new;
        $f->set('binmode',1|0);
        $f->set('PrintError',1|0);
        $f->set('RaiseError',1|0);
        $f->set('Trace',1|0);
        $f->set('f_dir',$dir|$dir_array)

       <  input, fail if doesn't exist >  output, truncate if exists, create
       if doesn't >> append, create if doesn't exist +< read/write, fail if
       doesn't exist

       r  = < r+ =

new()
        my $f = AnyData::Storage::File->new;

        or

        my $f = AnyData::Storage::File->new( %flags );

        %flags is a hash which can contain any or all of:

            f_dir      => $directory,   # defaults to './' (
            binmode    => $binmode,     # defaults to 0 (doesn't binmode files)
            printError => $warnings,    # defaults to 1 (print warning on errors)

open_local_file( $fname, $mode );
        Mode is one of

        a = append     open for reading & writing, create if doesn't exist
        r = read       open for reading, fail if doesn't exist
        u = open       open for reading & writing, fail if doesn't exist
        c = create     open for reading & writing, fail if it already exists
        o = overwrite  open for reading & writing, overwrite if it already exists

        Additionally, all modes fail if the file can't be opened.  On systems
        that support flock, 'r' fails if a shared lock can not be obtained; the
        other modes fail if an exclusive lock can't be obtained.
