As described on https://docs.python.org/dev/library/venv.html#creating-virtual-environments

[Global/Quartus2] Remove template

I haven't found good documentation for this file online, but it is a user based file that should be ignored.

Add 'build' directory to Symfony.gitignore

Update Dart.gitignore

Adding additional comments

add the `.pub/` directory, and change the `packages` filter to match sub-folders.

Update Jekyll.gitignore

Create GitBook.gitignore

Ignore user-specific rproj files instead of project-specific ones

Laravel4 is the current standard.

This resolves the name with the custom Laravel.gitignore file in the
gitignore.io project. If support for Laravel3 is desired, it should be done in
a new file: "Laravel3.gitignore

[Sublime Text] Adding cache files and binary files

Add .gitignore rules for Symfony3

The templare hasn't been touched since it was added and the project itself
hasn't been updated much since then either:

Symfony3 (and some versions of Symfony2) come with a new directory structure.
This updated version of Symfony.gitignore supports this new directory structure

supported.

Add in rule for .buildlog

Added recommended gitignore rules from Craft

added: rules for ignoring precompiled headers for C/C++

Quoting from http://symfony.com/legacy

  The symfony 1.x branch of the framework started in 2005 and the latest stable

  symfony 1.x is not maintained anymore and you are encouraged to have a look
  at Symfony2 for any new projects.
