You will have to rename config.pl.dist to config.pl (if you do not already have a config file in place). To do this through the shell, type: mv config.pl.dist config.pl
Now open up config.pl in your favorite editor (mine is vi) and modify the variables to your liking. The config file is very well documented, however feel free to ask any questions you may have on the discussion page.
Here are all the variables that can be set within config.pl. These are also documented with comments within the default config.pl.dist file, but are available here for reference.
$DataDir - This setting tells Aneuch where to store its data. It defaults to '/tmp/aneuch', which is probably not where you want it. Change this to point to a directory that your webserver has write access to (or if running SUExec, a directory that YOU can write to). All other directories that Aneuch uses will be created within this directory (i.e. pages, archive, etc). Note that you should not include the trailing slash. But if you do by mistake, Aneuch is sensible enough to remove it for you.
$SiteName - This is the name of your site, and defaults to 'Aneuch'. The site name will appear in the HTML title element, as well as in the footer of your site.
$SiteMode - This is quite possibly one of the most important settings you NEED to change. This variable controls if your site is wide open (anyone can post) or closed (only you can post). The default value is 0, which is wide open. Here is a list of potential values and what they mean:
@Passwords - This goes hand in hand with the $SiteMode variable above. If $SiteMode > 0, then you must set a password in this array to be able to allow someone to edit pages. As I mentioned, this is an array, so you can set it in one of the following manners:
$DefaultPage - This variable sets what is to be displayed by default if no page is requsted (for example, if a visitor merely types your website address, and does not include 'SomePage'). The default value is 'HomePage', and is a fairly sane default.
$DiscussPrefix - This variable determines the prefix that your discussion pages will use. The default is 'Discuss_', which means the discussion page for 'HomePage' would be 'Discuss_HomePage'. This is a sane default.
$CookieName - This variable tells your browser what to save the authentication cookie as, and defaults to 'Aneuch'. This is NOT a sane default, and should be changed. You should avoid using anything but alphanumeric values in this variable. An example: 'MySiteC0oki3'
$TimeZone - This variable controls how Aneuch will display time elements, but it might not quite work how you expect it to. This variable is numeric, allowing either a 0 or 1. The default value of 0 means that times on your wiki are UTC or GMT. This is probably not a bad idea if your wiki will entertain contributors from around the world. If you set this to 1, it will default to the local time zone of your server.
$LockExpire - When a user is editing an existing page, it is locked for editing by other users. If the user who has locked the page carelessly navigates away from the page, or simply walks away from his desk, the file remains locked forever. This variable exists to prevent such an event from happening. It sets the maximum amount of time a lock is valid, in seconds. Once this time has lapsed, the lock is released, and others are allowed to edit once again. The default value is 60*5, which is 300 seconds, or 5 minutes. This is a fairly sane default. You may want to adjust it based on your particular site's usage patterns.
$MaxVisitorLog - This variable controls the maximum amount of entries in your visitor log file before it starts getting trimmed. The default value is 1,000 entries, and is considered a sane default. Feel free to adjust this to your particular site's need. Set it to 0 to disable the visitor log.
$CountPageVisits - This variable controls whether or not Aneuch will keep a count of how many times a page has been visited. Possible values are 1 (true) and 0 (false). The default is true, and is considered a sane default.
$NewPage - This variable controls what is shown to users who visit a link within your wiki that leads to a page that has not been created yet. The default value is '<p>It appears that there is nothing here.</p>'
$NewComment - This variable controls what is shown in the comment textarea on your site. The default is 'Add your comment here.'
$NavBar - This variable sets anything additional you want to display in the links across the top of your page, in addition to what is set by $DefaultPage as well as "RecentChanges". The default is nothing, however you could set this to something like:
@NavBarPages - This array holds a list of pages that you want to appear in the nav bar, and is a replacement for the $NavBar variable above. It significantly simplifies the way the navbar is built. The default value is empty. If you want to include an "About" and a "Contact" page to your navbar, use this as an example:
$Debug - This variable controls whether or not error messages should be shown at the bottom of the page, and is really only useful to developers. The default is 0, which will not show errors. Set to 1 to see errors.
$RemoveOldTemp - This variable controls how long temp files are allowed to hang out in the temp folder. It contains a number of seconds. The default value is 7 days, or 60*60*24*7 (604,800) seconds, and is considered a sane default.
$PurgeRC - This variable controls how long an item may stay on the Recent Changes list. It contains a number of seconds. The default value is 7 days, or 60*60*24*7 (604,800) seconds, and is considered a sane default.
$PurgeArchives - This variable controls how long an archived page can stick around. Each time a modification is made, the "old" version of the page is archived. The default is to keep all (-1), and is considered a sane default. Set this to -1 to 0 to keep no revisions, or x number of seconds (for example, 60*60*24*30 for 30 days).
$PostFooter - This variable controls "extra" for the tail end of the footer. The default value is blank, and is considered a sane default.
$FancyUrls - This variable sets whether or not Aneuch will use 'fancy urls' in conjunction with .htaccess. If this is false (0), the URLs will show /aneuch.pl?Page (or whatever your script name is), if set to true (1) it would be /Page. The default is 1, and is considered sane assuming you have .htaccess configured (see htaccess.dist). Set it to 0 if you do not wish to use .htaccess or prefer to use the scriptname?Page method.
%QuestionAnswer - This hash holds the questions/answers for the anti-spam textcha. Questions will only be asked of those who are not authenticated. If you set this hash to be empty, no question will ever be asked (be warned that this will open your wiki up to getting spammed if you allow open editing). The default set of questions is sane, however you may want to change them, or add your own, as spambots will likely figure out the default set of questions.
$SurgeProtectionTime - This variable controls the number of time, in seconds, to check the visitor log for visits from the same IP address. The default is 20 seconds, and should be considered a sane default.
$SurgeProtectionCount - This variable controls the number of hits in the amount of time defined by $SurgeProtectionTime which will trigger the surge protection. The default is 20 hits, and should be considered a sane default.
$EditorLicenseText - This variable contains the text that will display just below the page editor, if set. It should be something explaining the licensing that your site uses in regards to its textual content. It is surrounded by paragraph tags in HTML. The default value is blank, and is a sane default.
$UploadsAllowed - This variable sets whether or not files can be uploaded to the wiki. The default value is 0, which disables uploads, and is considered a sane default. Set it to 1 to allow file uploads.
@UploadTypes - This array holds the MIME types that can be uploaded if file uploads are allowed. The default is set to include 'image/jpeg', 'image/gif', and 'image/png', and is considered a sane default.
$PurgeDeletedPage - This variable controls how long a deleted page can stick around (in seconds). The default is 2 weeks, and is consdered a sane default.
$ConfFile - Note that this variable is optional. Aneuch will use the current directory that it resides in to find the configuration file. However, it will not look anywhere else if it does not find one there. Now obviously it makes absolutely no sense whatsoever to set this variable within the configuration file itself. The only place it would be sensible is if you called aneuch.pl from within a wrapper.
