 =head1 Apache::Authn::SoundSoftware
 SoundSoftware - a mod_perl module for Apache authentication against a
 Redmine database and optional LDAP implementing the access control
 rules required for the SoundSoftware.ac.uk repository site.
 =head1 SYNOPSIS
 This module is closely based on the Redmine.pm authentication module
 provided with Redmine.  It is intended to be used for authentication
 in front of a repository service such as hgwebdir.
 Requirements:
 . Clone/pull from repo for public project: Any user, no
 authentication required
 . Clone/pull from repo for private project: Project members only
 . Push to repo for public project: "Permitted" users only (this
-:0c83d98252d9
+probably means project members who are also identified in the hgrc web
 section for the repository and so will be approved by hgwebdir?)

+=head1 INSTALLATION
 Debian/ubuntu:
   apt-get install libapache-dbi-perl libapache2-mod-perl2 \
     libdbd-mysql-perl libauthen-simple-ldap-perl libio-socket-ssl-perl
 Note that LDAP support is hardcoded "on" in this script (it is
 optional in the original Redmine.pm).
 =head1 CONFIGURATION
    ## This module has to be in your perl path

        SoundSoftwareDbUser "redmine"
        SoundSoftwareDbPass "password"
        Options +ExecCGI
        AddHandler cgi-script .cgi
        ## Optional where clause (fulltext search would be slow and
        ## database dependant).
        # SoundSoftwareDbWhereClause "and members.role_id IN (1,2)"

 #                  identical, under Windows you can do what you want.
 #                  This scripts help you, to keep an exact case in your
 #                  project.
 #          exact - internal links are only generated, when case of file
 #                  name and in source code are identical
 #            all - case doesn't matter
 #     exactupper - same as exact, additionally links are also vreated to
 #                  all upper case function names in source code (often
 #                  used by Mathworks)
 #      exactvery - same as exact, additionally info about not matching
 #                  case is written to screen (stdout), this can be very
 #                  helpful in cleaning up the case in a project

 # History: 06.03.1996  file created
 #          07.03.1996  first working version
 #          08.03.1996  modularized, help text only once included
 #          11.03.1996  clean up, some functions rwritten
 #          18.04.1996  silent output with writing in one line only
 #                      version 0.20 fixed
 #          14.05.1996  start of adding tree structure, could create tree
 #          15.05.1996  creating of index files for every directory
 #          17.05.1996  first working version except compact A-Z index
 #          20.05.1996  cleanup of actual version, more variables and
 #                      configurable settings
 #          21.05.1996  reading, update and creation of contents.m added
 #          22.05.1996  creation of short index started
 #          28.05.1996  jump letters for short index,
 #                      3 different directory indexes (short/long/contents)
 #          29.05.1996  major cleanup, short and long index created from one function
 #                      links for HTML and Indexes from 1 function,
 #                      version 0.9
 #          30.05.1996  contents.m changed to Contents.m (because unix likes it)
 #                      function definition can be in first line of m file before comments
 #                      version 0.91 fixed
 #          03.06.1996  contents file can be written as wanted, the links will be correct
 #                      cross references in help block of m-file will be found and
 #                      converted, even if the name of the function is written upper case
 #                      version 0.92 fixed
 #          05.06.1996  construction of dependency matrix changed, is able now to process
 #                      even the whole matlab tree (previous version needed to much memory)
 #                      removed warning for contents files in different directories
 #                      version 0.94 fixed
 #          06.06.1996  new link name matrices for ConstructHTMLFile created,
 #                      everything is done in ConstructDependencyMatrix,
 #                      both dependencies (calls and called) and matrix
 #                      with all mentioned names in this m-file, thus, much
 #                      less scanning in html construction
 #                      script is now (nearly) linear scalable, thus, matlab-toolbox
 #                      tree takes less than 1 hour on a Pentium120, with source
 #                      version 0.96 fixed
 #          10.06.1996  order of creation changed, first all indexes (includes
 #                      update/creation of contents.m) and then ConstructDepency
 #                      thus, AutoAdd section will be linked as well
 #                      excludenames extended, some more common word function names added
 #                      version 0.97 fixed
 #          17.02.1998  writecontentsm as command line parameter added
 #                      error of file not found will even appear when silent
 #                      version 1.02
 #          21.05.2000  mark comments in source code specially (no fully correct,
 #                      can't handle % in strings)
 #                      version 1.11
 #          05.11.2000  link also to upper and mixed case m-files
 #                      searching for .m files now really works (doesn't find grep.com any longer)
 #                      file renamed to mtree2html2001
 #                      generated html code now all lower case
 #                      inclusion of meta-description and meta-keywords in html files
 #                      HTML4 compliance done (should be strict HTML4.0, quite near XHTML)
 #                      version 1.23

    $PROGRAM v$VERSION - generate html documentation from Matlab m-files
    Usage: $PROGRAM [-h] [-c config_file] [-m|dirmfiles matlab_dir] [-d|dirhtml html_dir]
                    [-i yes|no] [-r yes|no] [-p yes|no] [-quiet|q] [-a authorfile]
    $PROGRAM is a perl script that reads each matlab .m file in a directory
    to produce a corresponding .html file of help documentation and cross
    reference information. An index file is written with links to all of
    the html files produced. The options are:
       -quiet         or -q : be silent, no status information during generation
       -help          or -h : display this help message
       -todo          or -t : print the todo list for $PROGRAM
       -version       or -v : display version
       -configfile    or -c : name of configuration file (default to $var{'configfile'}).
       -dirmfiles     or -m : top level directory containing matlab files to generate html for;
                              default to actual directory.
       -dirhtml       or -d : top level directory for generated html files;
                              default to actual directory.
       -includesource or -i : Include matlab source in the html documentation [yes|no]
                              default to yes.
       -processtree   or -r : create docu for m-file directory and all subdirectories [yes|no];
                              default to yes.
       -producetree   or -p : create multi-level docu identical to directory structure
                              of m-files [yes|no]; default to yes.
       -writecontentsm or -w: update or write contents.m files into the matlab source
                              directories [yes|no]; default to no.
       -authorfile    or -a : name of file including author information, last element in html;
                              default to empty.
    The command line setting overwrite all other settings (built-in and configuration file).
    The configuration file settings overwrite the built-in settings (and not the command
    line settings).
    Typical usages are:
      $PROGRAM
         (use default parameters from perl script, if configuration
          file is found -> generation of docu, else display of help)
      $PROGRAM -dirmfiles matlab -dirhtml html
         (generate html documentation for all m-files in directory matlab,
          place html files in directory html, use built-in defaults for
          all other parameters, this way all m-files in the directory
          matlab and below are converted and the generated html-files are
          placed in the directory html and below producing the same
          directory structure than below matlab)
      $PROGRAM -quiet
         (use built-in parameters from perl script, if configuration
          file is found use these settings as well, do generation,
          no display except critical errors, status of conversion and result)
      $PROGRAM -m toolbox -dirhtml doc/html -r yes -p no
         (convert all m-files in directory toolbox and below and place
          the generated html files in directory doc/html, read all m-files
          recursively, however, the generated html files are placed in one
          directory)
      $PROGRAM -m toolbox -dirhtml doc/html -i no -r no
         (convert all m-files in directory toolbox and place
          the generated html files in directory doc/html, do not read m-files
          recursively, do not include source code in documentation)

 # == Arguments (mandatory)
+#
-:7658d21a1493
+#   -s, --scm-dir=DIR         use DIR as base directory for repositories
-:513646585e45
+#   -r, --redmine-host=HOST   assume Redmine is hosted on HOST. Examples:
 #                             -r redmine.example.net
 #                             -r http://redmine.example.net
 #                             -r https://example.net/redmine
-:cbb26bc654de
+#   -k, --key=KEY             use KEY as the Redmine API key (you can use the
 #                             --key-file option as an alternative)
-:513646585e45
+            Chris
 # == Options
+#
 #   -o, --owner=OWNER         owner of the repository. using the rails login
 #                             allow user to browse the repository within
 #                             Redmine even for private project. If you want to
 #                             share repositories through Redmine.pm, you need
 #                             to use the apache owner.
 #   -g, --group=GROUP         group of the repository. (default: root)
 #   --scm=SCM                 the kind of SCM repository you want to create (and
 #                             register) in Redmine (default: Subversion).
 #                             reposman is able to create Git and Subversion
 #                             repositories. For all other kind, you must specify
 #                             a --command option
 #   -u, --url=URL             the base url Redmine will use to access your
 #                             repositories. This option is used to automatically
 #                             register the repositories in Redmine. The project
 #                             identifier will be appended to this url. Examples:
 #                             -u https://example.net/svn
 #                             -u file:///var/svn/
-:12420e46bed9
+#                             if this option isn't set, reposman will register
 #                             the repositories with local file paths in Redmine
-:513646585e45
+#   -c, --command=COMMAND     use this command instead of "svnadmin create" to
 #                             create a repository. This option can be used to
 #                             create repositories other than subversion and git
 #                             kind.
 #                             This command override the default creation for git
 #                             and subversion.
-:80433603a2cd
+#   --http-user=USER          User for HTTP Basic authentication with Redmine WS
 #   --http-pass=PASSWORD      Password for Basic authentication with Redmine WS
-:cbb26bc654de
+#       --key-file=PATH       path to a file that contains the Redmine API key
 #                             (use this option instead of --key if you don't
 #                             the key to appear in the command line)
-:513646585e45
+#   -t, --test                only show what should be done
 #   -h, --help                show help and exit
 #   -v, --verbose             verbose
