|
# This file checks that after installation, all files of the package
|
|
# that start with a "#!" line will find their interpreter. Files that
|
|
# have a "#!" line with a non-existent interpreter will generate an
|
|
# error message if they are executable, and a warning message otherwise.
|
|
#
|
|
# Files are not allowed to use /bin/env or /usr/bin/env as an interpreter
|
|
# due the use dynamic paths and package developers not checking that they work.
|
|
# A classic example is: #!/usr/bin/env python
|
|
#
|
|
# User-settable variables:
|
|
#
|
|
# CHECK_INTERPRETER
|
|
# Whether this check should be enabled or not.
|
|
#
|
|
# Default value: "yes" for PKG_DEVELOPER, "no" otherwise.
|
|
#
|
|
# Package-settable variables:
|
|
#
|
|
# CHECK_INTERPRETER_SKIP
|
|
# The list of file patterns that are skipped by the check.
|
|
# All files in share/examples and share/doc are skipped as well.
|
|
#
|
|
# Default value: (empty)

# Example: share/package1/* share/package2/somefile
