-== Putting input files in the download directory ==
-
-To move an input file to the download directory, use
-{{{
-dir_hier_path filename
-}}}
-which prints the full pathname and creates the directory if needed (run this in the project's root directory).
-For example:
-{{{
-cp test_files/12ja04aa `bin/dir_hier_path 12ja04aa`
-}}}
-copies an input file from the test_files/ directory to the download directory hierarchy.

-[[PageOutline]]
-= Submitting jobs =
-
-To submit a job you must
-
- 1. Write XML 'template files' that describe the job's input and outputs (typically the same template files can be used for many jobs).
- 1. Create the job's input file(s), and put them in the right place (as determined by the file name) in the [DirHierarchy download directory hierarchy].
- 1. Invoke a BOINC function or script that submits the job.
-
-Once this is done, BOINC takes over: it creates one or more instances of the job,
-distributes them to client hosts, collects the output files.
-It [ValidateIntro validates] and
-[AssimilateIntro processes] the results,
-and deletes the input and output files.
-
-Typically, steps 2) and 3) are done by a [WorkGeneration work generator] program
-that creates lots of jobs.
-
-== Input and output template files == #templates
-
-An input template file has the form
-{{{
-<file_info>
-    <number>0</number>
-    [ <sticky/> ]
-    [ <nodelete/> ]
-    [ <report_on_rpc/> ]

-[ ... other files  ]

-}}}
-Elements and tags must be on separate lines as shown.
-The components are:
-
- '''<file_info>''':: describes an [BoincFiles#Fileproperties input file].
-  '''<open_name>''':: the physical name of the file.
-  '''<sticky/>''':: if present, the file remains on the client after job is finished.
-  '''<nodelete/>''':: if present, the file is not deleted from the server after job is completed.
-  '''<report_on_rpc/>''':: if present, report file in each scheduler request (sticky files)
-
- '''<file_ref>''':: describes [BoincFiles#Filereferences the way the file is referenced].
-  '''<open_name>''':: the logical name of the file
-  '''<copy_file>''':: if present, the file is copied into the job's slot directory
-
- '''<command_line>''':: The command-line arguments to be passed to the main program.
-
- '''<credit>'''::
-        The amount of credit to be granted for successful completion of this workunit.
-        Use this only if you know in advance how many FLOPs it will take.
-        Your [ValidationSimple validator] must use {{{get_credit_from_wu()}}}
-        as its compute_granted_credit() function.
-
- '''<rsc_fpops_est>''' etc.::
-        [JobIn Work unit attributes]
-
-An output template file has the form
-{{{
-<file_info>
-    <name><OUTFILE_0/></name>
-    <generated_locally/>
-    <upload_when_present/>
-    <max_nbytes>32768</max_nbytes>
-    <url><UPLOAD_URL/></url>
-</file_info>
-<result>
-    <file_ref>
-        <file_name><OUTFILE_0/></file_name>
-        <open_name>result.sah</open_name>
-        [ <optional>0|1</optional> ]
-        [ <no_validate>0|1</no_validate> ]
-    </file_ref>
-</result>
-}}}
-
-Elements and tags must be on separate lines as shown.
-The elements include:
-
- '''<file_info>''':: describes an output file.
- '''<name>''':: the physical file name.
-  Typically use <OUTFILE_0>, <OUTFILE_1> etc.;
-  this will be replaced with a generated name based on the job name.
-
- '''<file_ref>''' describes an the output file will be referenced by the application.
- '''<open_name>''':: the "logical name" by which your application will reference the file.
- '''<generated_locally/>''':: always include this for output files.
- '''<max_nbytes>''':: maximum file size.
-   If the actual size exceeds this, the file will not be uploaded,
-   and the job will be marked as an error.
- '''<url>''':: the URL of the file upload handler.
-  You may include this explicitly, or use '''<UPLOAD_URL/>'''
-  to use the URL in your project's config.xml file.
- '''<optional>''':: if 0 or absent, your application must create the file,
-  otherwise the job will be marked as an error.
- '''<no_validate>''':: if true, don't include this file in the result validation process
-  (relevant only if you are using the sample bitwise validator).
-
-Note: when a job is created, the name of its output template file is stored in the database.
-The file is read when instances of the job are created, which may happen days or weeks later.
-Thus, editing an output template file can affect existing jobs.
-If this is not desired, you must create a new output template file.
-
-You can safely remove a workunit template file after creating your last WU with it.
-However, you can't delete a result template file until any WU that refers to it is completed
-(i.e. no more replicas will be created).
