Subject: Configuration, gitignore - Ignore all at root except explicit allowlist (#787)
X-Git-Url: http://git.dev.opencascade.org/gitweb/?a=commitdiff_plain;h=fe2f7bc983f0382e2da3700670492044804d2465;p=occt.git

Configuration, gitignore - Ignore all at root except explicit allowlist (#787)

Add single-level rules to ignore everything at the repository root while whitelisting
essential config files and directories. Explicitly allow selected data subdirectories
and top-level src modules, and preserve deeper-level ignore rules.
