ScriptBasic Configuration File
ScriptBasic uses a configuration file to define it's environment and configure extensions. The configuration file must be converted to a binary format to be used with the interpreter. ScriptBasic has a command line option to compile your text formatted version of the configuration file.
scriba -k scriba.conf.txt
This will create a scriba.conf file in it's binary format in the current directory under Windows or the /etc/scriba directory under Linux. You can dump your binary version of the configuration file to the screen with the follwing command line option.
Note: The dump option will not restore the comments of the original configuration file nor the line breaks or spaces (except those in strings).
You can tell ScriptBasic to use an alternate configuration file by using the -f option.
scriba -f custom.conf mypgm.bas
The format of the text file version of the configuration information is simple. It contains the keys and the corresponding values separated by one or more spaces and new lines. Usually a key and the assigned value are written on a line. Lines starting with the character ; are comment. The values can be integer numbers, real numbers, strings and sub-configurations. Strings can either be single line started and terminated by a single " character or multi-line strings starting and ending with three """ characters, just like in the language ScriptBasic. Sub-configurations start with the character ( and are closed with the character ). The lists between the parentheses are keys and corresponding values.
Sub-configuration levels without keys is not permitted and should be commented out or removed.

Application Server Configuration
Note that scripts may change the working directory therefore all directories should be specified here full path. For example the directory names here do not include the drive c: or e: because I develop it on two machines and it was inconvenient to alter and recompile the config file each time I moved the source to the other machine. When I run a script that changes the drive the http daemon stops in a few seconds because the guard thread do not find the pid file and therefore tells the engine to stop.
