-## Travis-CI
+By using the submodule mechanism, your module will always use an
+explicit commit, i.e. a fixed version of the scripts.
+This ensures that any further development of the ci-scripts will
+never break existing use.
 
-### Features
+## This Repository
 
- -  Compile against different branches or releases of EPICS Base
+In addition to the scripts themselves (in the subdirectories),
- -  Use different versions of compilers (gcc, clang)
+this repository contains the test suite that is used to verify
- -  Cross-compile for Windows 32bit using MinGW and WINE
+functionality and features of the ci-scripts.
- -  Cross-compile for RTEMS 4.9 and 4.10
- -  Compile on MacOS
 
-### How to Use these Scripts
+You are welcome to use the test suite as a reference, but keep in
+mind that in your module the path to the scripts has one level more
+(e.g., `./travis/abc` here would be `./.ci/travis/abc` in your
+module).
+Also, a test suite might not show the same level of quality as an
+example.
 
- 1. Get an account on [Travis-CI](https://travis-ci.org/), connect
+## Features
-    it to your GitHub account and activate your support module's
-    repository. For more details, please refer to the
-    [Travis-CI Tutorial](https://docs.travis-ci.com/user/tutorial/).
-    Make sure to use `travis-ci.org` and not their `.com` site.
 
- 1. In your Support Module, add this respository as a Git Submodule
+ - Compile against different branches or releases of EPICS Base and
-    (name suggestion: `.ci`).
+   additional dependencies (modules like asyn, std, etc.).
-    ```
+
-    $ git submodule add https://github.com/epics-base/ci-scripts .ci
+ - Define settings files that declare sets of dependencies
+   with their versions and locations.
+
+ - Define hook scripts for any dependency.
+   Hooks are run on the dependency module before it is compiled, so
+   the module can be patched or further configured.
+
+ - Define static or shared builds (executables, libraries).
+
+ - Run tests (using the EPICS unit test suite).
+
+## Supported CI Services
+
+### Travis-CI
+ - Use different compilers (gcc, clang)
+ - Use different gcc versions
+ - Cross-compile for Windows 32bit and 64bit using MinGW and WINE
+ - Cross-compile for RTEMS 4.9 and 4.10 (Base >= 3.16.2)
+ - Compile on MacOS
+ - Built dependencies are cached (for faster builds)
+
+### AppVeyor
+ - Use different compilers (Visual Studio, MinGW)
+ - Use different Visual Studio versions: \
+  2008, 2010, 2012, 2013, 2015, 2017, 2019
+ - Compile for Windows 32bit and 64bit
+
+## How to Use the CI-Scripts
+
+ 1. Get an account on a supported CI service provider platform.
+    (e.g. [Travis-CI](https://travis-ci.org/),
+    [AppVeyor](https://www.appveyor.com/), Azure Pipelines...)
+
+    (More details in the specific README of the subdirectory.)
+
+ 2. In your Support Module, add this ci-scripts repository
+    as a Git Submodule (name suggestion: `.ci`).
+    ```bash
+    git submodule add https://github.com/epics-base/ci-scripts .ci
     ```
 
- 1. Create a Travis configuration by copying one of the examples.
+ 3. Create setup files for different sets of dependencies you
+    want to compile against. (See below.)
+
+    E.g., a setup file `stable.set` specifying
     ```
-    $ cp .ci/.travis.yml.example-full .travis.yml
+    MODULES=sncseq asyn
+
+    BASE=3.15
+    ASYN=R4-34
+    SNCSEQ=R2-2-8
     ```
+    will compile against the EPICS Base 3.15 branch, the Sequencer
+    release 2.2.8 and release 4.34 of asyn.
+    (Any settings can be overridden from the specific job configuration
+    in e.g. `.travis.yml`.)
 
- 1. Edit the `.travis.yml` configuration to include the jobs you want
+ 4. Create a configuration for the CI service by copying one of
-    Travis to run.
+    the examples provided in the service specific subdirectory
+    and editing it to include the jobs you want the service to run.
+    Use your setup by defining e.g. `SET=stable` in the environment of
+    a job.
 
- 1. Push your changes and check 
+ 5. Push your changes and check the CI service for your build results.
-    [travis-ci.org](https://travis-ci.org/) for your build results.
 
-## Releases and Numbering
+## Setup Files
+
+Your module might depend on EPICS Base and a few other support modules.
+(E.g., a specific driver might need StreamDevice, ASYN and the Sequencer.)
+In that case, building against every possible combination of released
+versions of those dependencies is not possible:
+Base (37) x StreamDevice (50) x ASYN (40) x Sequencer (51) would produce
+more than 3.7 million different combinations, i.e. build jobs.
+
+A more reasonable approach is to create a few setups, each being a
+combination of dependency releases, that do a few scans of the available
+"version space". One for the oldest versions you want to support, one or two
+for stable versions that many of your users have in production, one for the
+latest released versions and one for the development branches.
+
+## Setup File Syntax
+
+Setup files are loaded by the build scripts. They are found by searching
+the locations in `SETUP_PATH` (space or colon separated list of directories,
+relative to your module's root directory).
+
+Setup files can include other setup files by calling `include <setup>`
+(omitting the `.set` extension of the setup file). The configured
+`SETUP_PATH` is searched for the include.
+
+Any `VAR=value` setting of a variable is only executed if `VAR` is unset or
+empty. That way any settings can be overridden by settings in the main
+configuration (e.g., `.travis.yml`).
+
+Empty lines or lines starting with `#` are ignored.
+
+`MODULES=<list of names>` should list the dependencies (software modules)
+by using their well-known slugs, separated by spaces.
+EPICS Base (slug: `base`) will always be a dependency and will be added and
+compiled first. The other dependencies are added and compiled in the order
+they are defined in `MODULES`.
+Modules needed only for specific jobs (e.g., on specific architectures)
+can be added in the main configuration file by setting `ADD_MODULES`
+for the specific job(s).
+
+`REPOOWNER=<name>` sets the default GitHub owner (or organization) for all
+dependency modules. Useful if you want to compile against a complete set
+of dependencies forked into your private GitHub area.
+
+For any module mentioned as `foo` in the `MODULES` setting (and for `BASE`),
+the following settings can be configured:
+
+`FOO=<version>` Set version of the module that should be used. Must either
+be a *tag* name or a *branch* name. [default: `master`]
+
+`FOO_REPONAME=<name>` Set the name of the remote repository as `<name>.git`.
+[default is the slug in lower case: `foo`]
+
+`FOO_REPOOWNER=<name>` Set the name of the GitHub owner (or organization)
+that the module repository can be found under.
+
+`FOO_REPOURL="<url>"` Set the complete URL of the remote repository. Useful
+for dependencies that are not hosted on GitHub.
+
+The default URL for the repository is pointing to GitHub, under
+`$FOO_REPOOWNER` else `$REPOOWNER` else `epics-modules`,
+using `$FOO_REPONAME` else `foo` and the extension`.git`.
+
+`FOO_DEPTH=<number>` Set the depth of the git clone operation. Use 0 for a
+full clone. [default: 5]
+
+`FOO_RECURSIVE=YES/NO` Set to `NO` (or `0`) for a flat clone without
+recursing into submodules. [default is including submodules: `YES`]
+
+`FOO_DIRNAME=<name>` Set the local directory name for the checkout. This will
+be always be extended by the release or branch name as `<name>-<version>`.
+[default is the slug in lower case: `foo`]
+
+`FOO_HOOK=<script>` Set the name of a script that will be run after cloning
+the module, before compiling it. Working directory when running the script
+is the root of the targeted module (e.g. `.../.cache/foo-1.2`).
+[default: no hooks are run]
+
+`FOO_VARNAME=<name>` Set the name that is used for the module when creating
+the `RELEASE.local` files. [default is the slug in upper case: `FOO`]
+
+The ci-scripts module contains default settings for widely used modules, so
+that usually it is sufficient to set `FOO=<version>`.
+You can find the list of supported (and tested) modules in `defaults.set`.
+Feel free to suggest more default settings using a Pull Request.
+
+## Debugging
+
+Setting `VV=1` in your service configuration (e.g., `.travis.yml`) for a
+specific job will run the job with high verbosity,
+printing every command as it is being executed and switching the dependency
+builds to higher verbosity.
+
+For local debugging, you may set `CACHEDIR` to change the location for the
+dependency builds. [default is `$HOME/.cache`]

+
+## Frequently Asked Questions
+
+**How can I see what the dependency building jobs are actually doing?**
+
+Set `VV=1` in the configuration line of the job you are interested in.
+This will make all builds (not just for your module) verbose.
+
+**How do I update my module to use a newer release of ci-scripts?**
+
+Update the submodule in `.ci` first, then change your CI configuration
+(if needed) and commit both to your module. E.g., to update your Travis
+setup to release 2.2.1 of ci-scripts:
+```bash
+cd .ci
+git pull origin v2.2.1
+cd -
+git add .ci
+  # if needed:
+  edit .travis.yml
+  git add .travis.yml
+git commit -m "Update ci-scripts submodule to v2.2.1"
+```
+
+Check the example configuration files inside ci-scripts (and their
+changes) to see what might be needed and/or interesting to change
+in your configuration.
+
+**Why does running the scripts locally on my MacOS machine fail?**
+
+The ci-scripts for Travis-CI require Bash version 4.
+As Apple ships an older Bash for [political reasons][reddit.bash],
+you need to install a more recent Bash, e.g. using MacPorts
+or Homebrew.

+# AppVeyor Scripts for EPICS Modules
+
+## Features
+
+ - Use different compilers (Visual Studio, MinGW)
+ - Use different VS versions (2008, 2010, 2012, 2013, 2015, 2017, 2019)
+ - Compile for Windows 32bit and 64bit
+ - Create static libraries or DLLs (plus the matching executables)
+ - Create optimized or debug builds
+
+## How to Use these Scripts
+
+ 1. Get an account on [AppVeyor](https://www.appveyor.com/), connect
+    it to your GitHub account and activate your support module's
+    repository. For more details, please refer to the
+    [AppVeyor documentation](https://www.appveyor.com/docs/).
+
+ 2. Add the ci-scripts respository as a Git Submodule
+    (see [README](../README.md) one level above).
+
+ 3. Add settings files defining which dependencies in which versions
+    you want to build against
+    (see [README](../README.md) one level above).
+
+ 4. Create an AppVeyor configuration by copying one of the examples into
+    the root directory of your module.
+    ```
+    $ cp .ci/appveyor/.appveyor.yml.example-full .appveyor.yml
+    ```
+	
+ 5. Edit the `.appveyor.yml` configuration to include the jobs you want
+    AppVeyor to run.
+
+    AppVeyor automatically creates a build matrix with the following axes:
+    1. `configuration:` \
+    Select static or dynamic (DLL) as well as regular or debug builds.
+    2. `platform:` \
+    Select 32bit or 64bit processor architecture.
+    3. `environment: / matrix:` \
+    List of environment variable settings. Each list element (starting with
+    a dash) is one step on the axis of the build matrix.
+    
+    Your builds will take long.
+    
+    AppVeyor only grants a single worker VM - all jobs of the matrix are
+    executed sequentially. Each job will take around 10 minutes.
+    
+    The `matrix: / exclude:` setting can be used to reduce the number of
+    jobs. Check the [AppVeyor docs](https://www.appveyor.com/docs/build-configuration/#build-matrix)
+    for more ways to reduce the build matrix size.
+	
+ 6. Push your changes and check
+    [ci.appveyor.com](https://ci.appveyor.com/) for your build results.

+# Travis-CI Scripts for EPICS Modules
+
+## Features
+
+ - Use different compilers (gcc, clang)
+ - Use different gcc versions
+ - Cross-compile for Windows 32bit and 64bit using MinGW and WINE
+ - Cross-compile for RTEMS 4.9 and 4.10
+ - Compile on MacOS
+ - Released versions of dependencies are cached (for faster builds)
+
+## How to Use these Scripts
+
+ 1. Get an account on [Travis-CI](https://travis-ci.org/), connect
+    it to your GitHub account and activate your support module's
+    repository. For more details, please refer to the
+    [Travis-CI Tutorial](https://docs.travis-ci.com/user/tutorial/).
+    Make sure to use `travis-ci.org` and not their `.com` site.
+
+ 2. Add the ci-scripts respository as a Git Submodule
+    (see [README](../README.md) one level above).
+
+ 3. Add settings files defining which dependencies in which versions
+    you want to build against
+    (see [README](../README.md) one level above).
+
+ 4. Create a Travis configuration by copying one of the examples into
+    the root directory of your module.
+    ```
+    $ cp .ci/travis/.travis.yml.example-full .travis.yml
+    ```
+	
+ 5. Edit the `.travis.yml` configuration to include the jobs you want
+    Travis to run.
+
+    Build jobs are declared in the list following the `jobs: include:`
+    declaration. Each element (starting with `-` in column 3) defines the
+    settings for one build job. `env:` controls the setting of environment
+    variables,`dist:` specifies the Linux distribution,
+    `os:` the operating system.
+    Also see the comments in the examples for more hints, and the Travis-CI
+    documentation for more options and more details.
+	
+ 6. Push your changes and check
+    [travis-ci.org](https://travis-ci.org/) for your build results.
