How to use these files:

Find your Enemy Territory directory.
Inside, there will be an 'etpro' directory.
Inside of that, make a 'trickjump' directory.
Put these files inside of the 'trickjump' directory.

In the game, you can use these files with the tjl commands:
tjl_load <filename> <slot>
tjl_drawslot <slot>

So, for example:
tjl_load oasis5 0
tjl_drawslot 0

This will show the trickjump line for oasis5.

You can also create and share your own lines.  Type /tjl_info in the
console for info, or use /tjl_menu to open a menu with some of the commands.

All of these lines were recorded on lnatrickjumpbeta3.
