NAME

       Config::Find - Find configuration files in the native OS fashion

SYNOPSIS

         use Config::Find;

         my $filename=Config::Find->find;

         ...

         my $fn_foo=Config::Find->find( name => 'my_app/foo',
                                        mode => 'write',
                                        scope => 'user' );

         my $fn_bar=Config::Find->find( names => [qw(my_app/bar appbar)] );

         my $fh=Config::Find->open( name => 'foo',
                                    scope => 'global',
                                    mode => 'w' )

         my $fn=Config::Find->install( 'original/config/file.conf',
                                       name => 'foo' );

         my $fn=Config::Find->find( file => $opt_c,
                                    name => foo );

ABSTRACT

       Config::Find searches for configuration files using OS dependent heuristics.

DESCRIPTION

       Every OS has different rules for configuration files placement, this module allows one to
       easily find and create your app configuration files following those rules.

       Config::Find references configuration files by the application name or by the application
       name and the configuration file name when the app uses several application files, i.e
       "emacs", "profile", "apache/httpd", "apache/ssl".

       By default the $0 value is used to generate the configuration file name. To define it
       explicitly the keywords "name" or "names" have to be used:

       name => "name" or "app/file"
           picks the first configuration file matching that name.

       names => [qw(foo bar foo/bar)]
           picks the first configuration file matching any of the names passed.

       Alternatively, the exact position for the file can be specified with the "file" keyword:

       file => "/config/file/name.conf"
           explicit position of the configuration file.

           If undef is passed this entry is ignored and the search for the configuration file
           continues with the apropiate OS rules. This allows for:

             use Config::Find;
             use Getopt::Std;

             our $opt_c;
             getopts('c:');

             my $fn=Config::Find->find(file => $opt_c)

       Methods in this package also accept the optional arguments "scope" and "mode":

       scope => "user" or "global"
           Configuration files can be private to the application user or global to the OS, i.e.
           in unix there is the global "/etc/profile" and the user "~/.profile".

       mode => "read" or "write"
           In "read" mode already existant file names are returned, in "write" mode the file
           names point to where the configuration file has to be stored.

   METHODS
       All the methods in this package are class methods (you don't need an object to call them).

       $fn=Config::Find->find(%opts)
           returns the name of the configuration file.

       $fh=Config::Find->open(%opts)
           returns a open file handle for the configuration file. In write mode, the file and any
           nonexistant parent directories are created.

       $fn=Config::Find->install($original, %opts)
           copies a configuration file to a convenient place.

   EXPORT
       None, this module has an OO interface.

BUGS

       Some Win32 OSs are not completely implemented and default to inferior modes, but hey, this
       is a work in progress!!!

       Contributions, bug reports, feedback and any kind of comments are welcome.

       the configuration files.
