       Pak is a package manager for application components.

       Existing  package managers like NPM are excellent, but they are heavily
       focussed the needs of NodeJS and not for non-Node applications or  gen-
       eral application components. Pak is agnostic to its environment and can
       be used to install components for any application.

       Pak has the following major features:

           . Install, list and uninstall packages into a local application
           . Manages a local cache of retrieved packages
           . Provides a global catalog to search for public packages
           . Easy upgrading packages when new versions become available
           . Automatically retrieves and installs dependant packages
           . Supports the CommonJS package standard
           . Supports the SemVer package versioning standard
           . Supports using GitHub and NPM as the primary package repository
           . Retrieves packages using the Pak, NPM and Bower catalogs

       While Pak has a strong feature set, there are some characteristics that
       make Pak particularly sweet.

           . Fast, fast, fast.
           . Local cache of packages supports fast offline use.
           . Share packages by publishing to a common public catalog.
           . Catalog web portal to search published packages.
           .  Pak  integrates with the Bower repository to seamlessly download
       Bower components.
           . Package.json is compatible with nodejs.
           . Retrieve packs from NPM and bower.
           . Easy overriding to tailor packages from NPM and bower.

       To install packages:
           pak install Endpoints...

       Where an ENDPOINT can be the name of a package  published  in  the  Pak
       catalog,  NPM  or bower catalog, a GitHub repository endpoint, a GitHub
       account/repository or a path to a local package directory. For example:

           pak install jquery
           pak install pak:jquery
           pak install npm:jquery
           pak install bower:jquery
           pak install embedthis/exp-js
           pak install
           pak install
           pak install ./my-source/graphics

       To uninstall
           pak uninstall Endpoints...

       To list installed packages
           pak list

       To display package dependencies
           pak depend

       To  show  what  packages are present in the cache and where they origi-
           pak cached

       To download and cache a package but not install in the local directory
           pak cache Name

       To prune old versions from the cache
           pak prune

       A package is described by a CommonJS package.json file.  This  provides
       at a minimum the following properties.

                "name": "Package name - one word"
                "description": "Package description - one line"
                "version": "1.2.3",
                "keywords": [
                    "comms", "websockets", "sockets", "ssl",
                "author": {
                    "name": "Your name",
                    "email": "Your email",
                    "url": "Your web site"
                "bugs": {
                    "email": "",
                    "url": ""
                "license": "GPL",
                "dependencies": {
                    "name": "version"
                } }

       For more details, see:

       To  run  Pak  with  more  verbose  trace output, use the [-v] --verbose
       switch. To run with less trace, use the [-q] --quiet  switch.   To  run
       completely silently except for hard-errors, use --silent.

       To publish a new package, create a package.json and then run pak inside
       the directory of the package to be published:

           pak publish

       Where NAME is the name of package, REPOSITORY is the GitHub endpoint of
       the  package.  You  will  be prompted to enter a password to manage the
       package. You will need this password to modify or retract  the  package
       in the future.  Safeguard it well.

       On  startup,  Pak  reads  configuration  from  a  pakrc file. This file
       defines the operational configuration for Pak. For example:
           catalogs: {
               pak: {
                   list: '',
                   query:     '
                   download:          '${OWNER}/${NAME}/ar-
               bower: {
                   list: '',
                   query: '${NAME}',
                   download:          '${OWNER}/${NAME}/ar-
               npm: {
                   query: '${NAME}',
                   download:                                      'http://reg-${NAME}/-/${NAME}-${TAG}.tgz',
           "directories": {
               "paks": "paks",
               "pakcache": "~/.paks",

       The "catalogs" property defines sites that index and catalog packs. The
       "paks"  directory  is the name of the local directory in which to store
       packages. The "pakcache" directory defines where to cache  packages  on
       the local system.

       Pak locates a valid pakrc file by searching in order:

           pakrc, .pakrc, ../pakrc, ../.pakrc, /etc/pakrc, package.json

       cache [packages...]
              Download and populate the cache with packages.

       cached [packages...]
              List packages in the cache.

       config Show the Pak configuration.

       depend [packages...]
              Display installed package dependencies.

       edit key[=value]...

       init [name [version]]
              Create a new package.json.

       install packages...
              Install a package on the local system. The package name can be a
              name in an online catalog or it can be a GitHub endpoint URL  or
              of  the  form 'account/repositiory'. The package name may have a
              catalog prefix "pak", "npm" or "bower" to select a specific cat-
              alog  to  use when locating the package repository endpoint. Use
              the --write option to update the package.json dependencies  with
              the  install  package.  Use with the --optional switch to update
              the optionalDependencies.

       list [packages...]
              List the installed packages.

              Lockdown  the  version  criteria  for  all  dependencies.   This
              rewrites the package.json to define a compatible version expres-
              sion for all installed dependencies.

       mode   Index in the modes property. The selected property collection is
              copied up to the top level. This may be used to select a "debug"
              or "release" configuration.

       prune [packages...]
              Prune named packages.

       publish name endpoint password

              Unpublish a package.

       search packages...
              Search for packages in the catalogs.

              Uninstall an installed package. Use --write to remove  from  the
              package dependencies.

       update [packages...]
              Update  the pak cache with latest available version of the pack-
              age. This will check with catalogs to determine the most  recent
              versions  of a package and will download the package and save in
              the cache.

       upgrade [packages...]
              Upgrade installed packages with the latest version of the  pack-
              age.  This will update the cache if required.  Use --noupdate to
              upgrade only from the local cache without downloading  new  ver-

       version [major|minor|patch|other]
              Update  the version by incrementing the relevant major, minor or
              patch portion of the version string.  Alternatively, provide  an
              exact version string to set. Without any argument, 'pak version'
              will print the current version.

       --all URI
              Show all versions of a package.

       --cache directory
              Specify the directory to use for the paks cache. This  overrides
              the values specified in the various pakrc or package.json files.

       --details URI
              Show more package details. Useful with "pak list".

       --dir directory
              Change to the given directory before running.

              Force the command to continue. This  is  useful  to  install  or
              cache  a  package  when dependencies cannot be satisfied.  It is
              also useful to cache  or  install  an  already  cached/installed
              pack. Aliased as -f.

              --init  Initialize the directory by creating a package.json file
              if one does not already exist. The name of  the  application  is
              set to the basename of the directory.

       --log logName[:logLevel]
              Specify  a file to log internal execution messages. Bit will log
              execution related trace to the log file. The log level specifies
              the  desired  verbosity  of output. Level 0 is the least verbose
              and level 9 is the most. The '-v' switch is an alias for  '--log

              Used to suppress installing or upgrading dependent packages.

              Used when installing packages to add them to the 'optionalDepen-
              dencies' list instead of as a hard dependency.

       --paks directory
              Specify the local "paks" directory in which to install packages.
              This  overrides  the  values  specified  in the various pakrc or
              package.json files.

       --password file
              Specify the a file containing the password  to  use  when  doing
              "pak publish".

              Run in quiet mode with less verbose otuput. Aliased as -q.

              Run  in  silent mode suppressing all but hard errors. Aliased as

       --versions URI
              Show package version information.

       --write URI
              Write  installed  packages  to  package.json  dependencies.  Use
              --optional  to  update optionalDependencies.  When uninstalling,
              --write will remove the package from the dependencies and update
              the package.json.
