-create_resources
-----------------
-Converts a hash into a set of resources and adds them to the catalog.
-
-This function takes two mandatory arguments: a resource type, and a hash describing
-a set of resources. The hash should be in the form `{title => {parameters} }`:
-
-    # A hash of user resources:
-    $myusers = {
-      'nick' => { uid    => '1330',
-                  group  => allstaff,
-                  groups => ['developers', 'operations', 'release'], }
-      'dan'  => { uid    => '1308',
-                  group  => allstaff,
-                  groups => ['developers', 'prosvc', 'release'], }
-    }
-
-    create_resources(user, $myusers)
-
-A third, optional parameter may be given, also as a hash:
-
-    $defaults => {
-      'ensure'   => present,
-      'provider' => 'ldap',
-    }
-
-    create_resources(user, $myusers, $defaults)
-
-The values given on the third argument are added to the parameters of each resource
-present in the set given on the second argument. If a parameter is present on both
-the second and third arguments, the one on the second argument takes precedence.
-
-This function can be used to create defined resources and classes, as well
-as native resources.

-defined
--------
-Determine whether
-a given class or resource type is defined. This function can also determine whether a
-specific resource has been declared. Returns true or false. Accepts class names,
-type names, and resource references.
-
-The `defined` function checks both native and defined types, including types
-provided as plugins via modules. Types and classes are both checked using their names:
-
-    defined("file")
-    defined("customtype")
-    defined("foo")
-    defined("foo::bar")
-
-Resource declarations are checked using resource references, e.g.
-`defined( File['/tmp/myfile'] )`. Checking whether a given resource
-has been declared is, unfortunately, dependent on the parse order of
-the configuration, and the following code will not work:
-
-    if defined(File['/tmp/foo']) {
-        notify("This configuration includes the /tmp/foo file.")
-    }
-    file {"/tmp/foo":
-        ensure => present,
-    }
-
-However, this order requirement refers to parse order only, and ordering of
-resources in the configuration graph (e.g. with `before` or `require`) does not
-affect the behavior of `defined`.

-extlookup
----------
-This is a parser function to read data from external files, this version
-uses CSV files but the concept can easily be adjust for databases, yaml
-or any other queryable data source.
-
-The object of this is to make it obvious when it's being used, rather than
-magically loading data in when an module is loaded I prefer to look at the code
-and see statements like:
-
-    $snmp_contact = extlookup("snmp_contact")
-
-The above snippet will load the snmp_contact value from CSV files, this in its
-own is useful but a common construct in puppet manifests is something like this:
-
-    case $domain {
-      "myclient.com": { $snmp_contact = "John Doe <john@myclient.com>" }
-      default:        { $snmp_contact = "My Support <support@my.com>" }
-    }
-
-Over time there will be a lot of this kind of thing spread all over your manifests
-and adding an additional client involves grepping through manifests to find all the
-places where you have constructs like this.
-
-This is a data problem and shouldn't be handled in code, a using this function you
-can do just that.
-
-First you configure it in site.pp:
-
-    $extlookup_datadir = "/etc/puppet/manifests/extdata"
-    $extlookup_precedence = ["%{fqdn}", "domain_%{domain}", "common"]
-
-The array tells the code how to resolve values, first it will try to find it in
-web1.myclient.com.csv then in domain_myclient.com.csv and finally in common.csv
-
-Now create the following data files in /etc/puppet/manifests/extdata:
-
-    domain_myclient.com.csv:
-      snmp_contact,John Doe <john@myclient.com>
-      root_contact,support@%{domain}
-      client_trusted_ips,192.168.1.130,192.168.10.0/24
-
-    common.csv:
-      snmp_contact,My Support <support@my.com>
-      root_contact,support@my.com
-
-Now you can replace the case statement with the simple single line to achieve
-the exact same outcome:
-
-   $snmp_contact = extlookup("snmp_contact")
-
-The above code shows some other features, you can use any fact or variable that
-is in scope by simply using %{varname} in your data files, you can return arrays
-by just having multiple values in the csv after the initial variable name.
-
-In the event that a variable is nowhere to be found a critical error will be raised
-that will prevent your manifest from compiling, this is to avoid accidentally putting
-in empty values etc.  You can however specify a default value:
-
-   $ntp_servers = extlookup("ntp_servers", "1.${country}.pool.ntp.org")
-
-In this case it will default to "1.${country}.pool.ntp.org" if nothing is defined in
-any data file.
-
-You can also specify an additional data file to search first before any others at use
-time, for example:
-
-    $version = extlookup("rsyslog_version", "present", "packages")
-    package{"rsyslog": ensure => $version }
-
-This will look for a version configured in packages.csv and then in the rest as configured
-by $extlookup_precedence if it's not found anywhere it will default to `present`, this kind
-of use case makes puppet a lot nicer for managing large amounts of packages since you do not
-need to edit a load of manifests to do simple things like adjust a desired version number.
-
-Precedence values can have variables embedded in them in the form %{fqdn}, you could for example do:
-
-    $extlookup_precedence = ["hosts/%{fqdn}", "common"]
-
-This will result in /path/to/extdata/hosts/your.box.com.csv being searched.
-
-This is for back compatibility to interpolate variables with %. % interpolation is a workaround for a problem that has been fixed: Puppet variable interpolation at top scope used to only happen on each run.

-regsubst
---------
-Perform regexp replacement on a string or array of strings.
-
-* *Parameters* (in order):
-    * _target_  The string or array of strings to operate on.  If an array, the replacement will be performed on each of the elements in the array, and the return value will be an array.
-    * _regexp_  The regular expression matching the target string.  If you want it anchored at the start and or end of the string, you must do that with ^ and $ yourself.
-    * _replacement_  Replacement string. Can contain backreferences to what was matched using \0 (whole match), \1 (first set of parentheses), and so on.
-    * _flags_  Optional. String of single letter flags for how the regexp is interpreted:
-        - *E*         Extended regexps
-        - *I*         Ignore case in regexps
-        - *M*         Multiline regexps
-        - *G*         Global replacement; all occurrences of the regexp in each target string will be replaced.  Without this, only the first occurrence will be replaced.
-    * _encoding_  Optional.  How to handle multibyte characters.  A single-character string with the following values:
-        - *N*         None
-        - *E*         EUC

-
-require
--------
-Evaluate one or more classes,  adding the required class as a dependency.
-
-The relationship metaparameters work well for specifying relationships
-between individual resources, but they can be clumsy for specifying
-relationships between classes.  This function is a superset of the
-'include' function, adding a class relationship so that the requiring
-class depends on the required class.
-
-Warning: using require in place of include can lead to unwanted dependency cycles.
-
-For instance the following manifest, with 'require' instead of 'include' would produce a nasty dependence cycle, because notify imposes a before between File[/foo] and Service[foo]:
-
-    class myservice {
-      service { foo: ensure => running }
-    }
-
-    class otherstuff {
-      include myservice
-      file { '/foo': notify => Service[foo] }
-    }
-
-Note that this function only works with clients 0.25 and later, and it will
-fail if used with earlier clients.
