Maybe the outdated version will help:

For your specific question I see this in the docs,
"""
The Interactive Startup File
When you use Python interactively, it is frequently handy to have some standard
commands executed every time the interpreter is started. You can do this by
setting an environment variable named PYTHONSTARTUP to the name of a file
containing your start-up commands. This is similar to the .profile feature of
the Unix shells.
This file is only read in interactive sessions, not when Python reads commands
from a script, and not when /dev/tty is given as the explicit source of
commands (which otherwise behaves like an interactive session). It is executed
in the same namespace where interactive commands are executed, so that objects
that it defines or imports can be used without qualification in the interactive
session. You can also change the prompts sys.ps1 and sys.ps2 in this file.
If you want to read an additional start-up file from the current directory, you
can program this in the global start-up file using code like if
os.path.isfile('.pythonrc.py'): execfile('.pythonrc.py'). If you want to use
the startup file in a script, you must do this explicitly in the script:
import os filename = os.environ.get('PYTHONSTARTUP') if filename and
os.path.isfile(filename):
execfile(filename)

emded revision control in Python application?
Hello, I have an application that would benefit from collaborative working. Over time users construct a "data environment" which is a number of files in JSON format contained in a few directories (in the future I'll probably place these in a zip so the environment is contained within a single file). At the moment there is one individual constructing the data environment, and me occasionally applying corrections after being e-mailed the files. But in the future there might be several individuals in various locations. As a minimum requirement I need to embed some sort of version control, so that changes committed by one individual will be seen in the local environments of the others. Some of the work involves editing graphs which have restrictions on their structure. In this case it would be useful for edits to be committed / seen in real time. The users will not be particularly technical, so the version control will have to happen relatively quietly in the background. My immediate thoughts are to (somehow) embed Mercurial or Subversion. It would certainly be useful to be able to revert to a previous version of the data environment if an individual does something silly. But I'm not actually convinced that this is the whole solution for collaborative working. Any advice regarding the embedding of a version control system or alternative approaches would be appreciated. I haven't tried anything like this before. The desktop application is written in Python (2.6) with a wxPython (2.8) GUI. Given the nature of the application / data the machines involved might be locally networked but without web access (if this makes a difference). TIA.

Why not just stick the configs (binary blob or JSON string) in something like a sqlite database and store that database centrally accessible[1]? Something like subversion might be overkill. A table like the following would work if you want to track each file separately: table_name( revision_number, file/config name, data, username, timestamp ). Otherwise, if you want to track "environments" and not files: table_name( revision_number, data, username, timestamp ). Where revision number can be a sequence used to track / change current configuration. I recommend storing each file separately in the database.

That applies to Perl, Python, Java and probably most major languages. I do not know about you, but I do not want to be writing everything from scratch and language developers have better things to do than implementing a dozen (or more) major libraries like lxml and xlwt just to name a few. For that matter, I do not think mysqldb is a built-in Python package. :) Ramit Ramit Prasad | JPMorgan Chase Investment Bank | Currencies Technology 712 Main Street | Houston, TX 77002 work phone: 713 - 216 - 5423 -- This email is confidential and subject to important disclaimers and conditions including on offers for the purchase or sale of securities, accuracy and completeness of information, viruses, confidentiality, legal privilege, and legal entity disclaimers, available at http://www.jpmorgan.com/pages/disclosures/email. -- http://mail.python.org/mailman/listinfo/python-list

Over time users construct a "data environment" which is a number of files in JSON format contained in a few directories So, will the users modify their local environment and you'd push the revisions to a known location for redistribution? Yes. My rough idea is that each time a user opens the application it will connect to a server and download the current data environment (or preferably just the changes made since the application was last connected). Thus the user can start with an up to date environment. As the application is used to make changes to the data environment any changes are uploaded to the server for immediate redistribution to other connected application instances. Part of the application involves the construction of directed acyclic graphs. If I add an edge to a graph I want anyone else editing the same graph to be able to see the edge in something approaching real time so that cycles are avoided. (Being able to lock the file so that only one user can edit it concurrently might be another solution to this specific issue.) How might peer-to-peer work? How would you know which peers get the change, or would all peers get the change? All peers. I'm not sure about the peer to peer thing though. It would be better if the user could be guaranteed that the environment they see is current, rather than having changes residing on someone else's machine that happens to be switched off. I suppose the alternative must be that the information is sat on a server somewhere. I've been working with rpyc (in as much spare time as I can manage) on some similar sounding issues and am now settling on a central system which provides convenient administration and potential relaying or pulling.
