# The distutils.ccompiler module doesn't allow the runtime addition of compiler
# classes that live outside the distutils package, and of course it doesn't
# recognize the D language and its associated compilers by default.
# This module hot-patches distutils.ccompiler to overcome those limitations.
# To apply these changes, the file for extension modules written in D
# should execute the following import statement:
#   from celerid import patch_distutils

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.

Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
