+This directory contains configuration files to ignore errors found in
+the build and test process which are known to the developers and for
+now can be safely ignored.
+
+To use:
+
+ $ cd zephyr
+ $ make SOMETHING >& result
+ $ scripts/filter-known-issues.py result
+
+It is included in the source tree so if anyone has to submit anything
+that triggers some kind of error that is a false positive, it can
+include the "ignore me" file, properly documented.
+
+Each file can contain one or more multiline Python regular expressions
+(https://docs.python.org/2/library/re.html#regular-expression-syntax)
+that match an error message. Multiple regular expressions are
+separated by comment blocks (that start with #). Note that an empty
+line still is considered part of the multiline regular expression.
+
+For example
+
+---beginning---
+#
+# This testcase always fails, pending fix ZEP-1234
+#
+.*/tests/kernel/grumpy .* FAIL
+#
+# Documentation issue, masks:
+#
+# /home/e/inaky/z/kernel.git/doc/api/io_interfaces.rst:28: WARNING: Invalid definition: Expected identifier in nested name. [error at 19]
+#  struct dev_config::@65  dev_config::bits
+#  -------------------^
+#
+^(?P<filename>.+/doc/api/io_interfaces.rst):(?P<lineno>[0-9]+): WARNING: Invalid definition: Expected identifier in nested name. \[error at [0-9]+]
+^\s+struct dev_config::@[0-9]+  dev_config::bits.*
+^\s+-+\^
+---end---
+
+Note you want to:
+
+- use relateive paths; instead of
+  /home/me/mydir/zephyr/something/somewhere.c you will want
+  ^.*/something/somewhere.c (as they will depend on where it is being
+  built)
+
+- Replace line numbers with [0-9]+, as they will change
+
+- (?P<filename>[-._/\w]+/something/somewhere.c) saves the match on
+  that file path in a "variable" called 'filename' that later you can
+  match with (?P=filename) if you want to match multiple lines of the
+  same error message.
+
+Can get really twisted and interesting in terms of regexps; they are
+powerful, so start small :)

+## Our Responsibilities
 
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
 
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
+Project maintainers have the right and responsibility to remove, edit, or

 ## Scope
 
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
 
 ## Enforcement
 
 Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-conduct@zephyrproject.org. Reports will be received by the Chair of the Zephyr
-Governing Board, the Zephyr Project Director (Linux Foundation), and the Zephyr
-Project Developer Advocate (Linux Foundation). You may refer to the [Governing
-Board](https://zephyrproject.org/governing-board/) and [Linux Foundation
-Staff](https://zephyrproject.org/staff/) web pages to identify who are the
-individuals currently holding these positions.
-All complaints will be reviewed and investigated promptly and fairly.
+reported by contacting the project team at conduct@zephyrproject.org.
+Reports will be received by Kate Stewart (Linux Foundation) and Amy Occhialino
+(Intel). All complaints will be reviewed and investigated, and will result in a
+response that is deemed necessary and appropriate to the circumstances. The
+project team is obligated to maintain confidentiality with regard to the
+reporter of an incident.  Further details of specific enforcement policies may
+be posted separately.
 
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
