Project structure

Special branches

SCM based on Git-flow

Branch membership is determined by a series of branch specific .gitignore files based on the configuration here.

content: all source data needed to "initialize" a drush site-install. At build time, drush make will download this branch from a private server

config/: stage specific settings for capistrano, drush, and supporting services, along with templates.
exports: serialized config dumps from the database
htdocs: automatically created during local builds, or when a remote build is downloaded locally; is also ignored by git
lib: plugins and extension to dev tooling
libraries: contrib module dependencies
modules/content: content branch specific modules and data
modules/custom: custom modules not yet broken-out into their own projects, so are bundled with the profile here
modules/dev: developer tooling
modules/features: site specific configuration
modules/migrations: import/export migrations from older sites, also intra-release migrations between major versions
modules/updates: experimental meta-code for programmatically altering features
patches: build specific patches to core and/or contrib
theme: bundled themes
