The install.sh file for each framework starts the bash process which will install that framework. Typically, the first thing done is to call fw_depends to run installations for any necessary software that TFB has already created installation scripts for. TFB provides a reasonably wide range of core software, so your install.sh may only need to call fw_depends and exit. Note: fw_depends does not guarantee dependency installation, so list software in the proper order e.g. if foo depends on bar use fw_depends bar foo.

Here are some example install.sh files

#!/bin/bash

# My framework only needs nodejs
fw_depends nodejs

#!/bin/bash

# My framework needs nodejs and mono and go
fw_depends nodejs mono go

#!/bin/bash

# My framework needs nodejs
fw_depends nodejs

# ...and some other software that there is no installer script for.
# Note: Use IROOT variable to put software in the right folder. 
#       You can also use FWROOT to refer to the project root, or 
#       TROOT to refer to the root of your framework
# Please see guidelines on writing installation scripts
wget mystuff.tar.gz -O mystuff.tar.gz
untar mystuff.tar.gz
cd mystuff
make --prefix=$IROOT && sudo make install

To see what TFB provides installations for, look in toolset/setup/linux in the folders frameworks, languages, systools, and webservers. You should pass the filename, without the ".sh" extension, to fw_depends. Here is a listing as of July 2014:

$ ls frameworks
