This is what I've done:
cd Downloads
tar -jxvf renpy-6.99.3-sdk.tar.bz2
./configure
And the result was:
bash: ./configure: No such file or directory
The renpy-6.99.3-sdk folder contains the following folders:
doc launcher lib module renpy renpy.app templates the_question tutorial update
And the following archives:
LICENSE.txt renpy.exe renpy.py renpy.sh
...
I've tried this:
cd Downloads
tar -jxvf renpy-6.99.3-sdk.tar.bz2
cd renpy-6.99.3-sdk
./configure
But the result is the same.
