Shell Log.md

Shell script to make producing tool_dependencies easier. It's simple to use, behaves a lot like a venv, and then produces a tool_dependencies.xml in the directory where you started when you deactivate at the end.

Pretty to activate:

. activate.sh

Example of use:

esr@cpt:~/⟫ . activate.sh
(remember-me) esr@cpt:~/⟫ wget http://hgdownload.soe.ucsc.edu/admin/jksrc.v312.zip
(remember-me) esr@cpt:~/⟫ unzip jksrc.v312.zip
(remember-me) esr@cpt:~/⟫ cd kent/src/lib/
(remember-me) esr@cpt:~/kent/src/utils⟫ make
...
(remember-me) esr@cpt:~/kent/src/utils⟫ mv x86_64/jkweb.a $INSTALL_DIR/lib/
# TODO, right now we just let this fail
(remember-me)130 esr@cpt:~/kent/src/utils⟫ cd ../utils/
(remember-me)130 esr@cpt:~/kent/src/utils⟫ make

(remember-me)130 esr@cpt:~/kent/src/utils⟫ deactivate 
Package Name: kent

                <action type="change_directory">kent/src/lib/</action>
                <action type="shell_command">make</action>

                <action type="shell_command">make</action>
            </actions>
        </install>
        <readme>
        </readme>
    </package>

Very nice idea!
