+### 1.01 Introduction
+
+CleanerML was designed and written by Andrew Ziem from BleachBit.org for BleachBit.  
+But the documentation and the CleanerML files are open and therefor can be used by any program that fulfill the license.  
+CleanerML is a XML-based markup language to write platform independend system cleaners.  
+CleanerML is still under development and new features get added.

+
+### 1.02 The Editor
+
+If you be a Windows User, we recommend you to use Notepad++ as editor of choice!  
+Notepad++ is Open Source, too and have a wonderfull code highlighting for XML files and therefor your coding experience get much more colored and visual.  
+Notepad++ is available for download here: https://notepad-plus-plus.org/
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 1.03 Be pretty
+
+**Coding style:**  
+We use the coding style that xmllint (Linux Program) use! (More to xmllint at the end of this docu...)
+
+**The coding style is:**  
+- Throw in with two spaces;  
+- Comments can have multiple lines;  
+- Comments are done in new lines;  
+- And no empty lines in code!
+- Cleaner and option IDs are written in small letters;
+- Underscore is the conventonal delimiter rather than a dash.
+
+XML files get in repo later formated/tested with xmllint...

+
+### 1.04 Python & "glob" (Unix style pathname pattern expansion)
+
+According to https://docs.python.org/3/library/glob.html:
+The `glob` module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell, [...].
+No tilde expansion is done, but `*`, `?`, and character ranges expressed with `[]` will be correctly matched. [...]
+Note that [...] glob treats filenames beginning with a dot (`.`) as special cases. [...]  
+For a literal match, wrap the meta-characters in brackets. For example, `'[?]'` matches the character `'?'`.  
+
+And now the same a bit more simple:  
+In *NIX Systems (Linux, Unix, BSD, Darvin, ...) paths and file names can contain special characters like `*` and `?`.  
+To use now wildcard or interrogation mark for a Windows-like search, we have to use in this cases `glob`!  
+In the following there will be here and there some cases & examples in the documenation, where `glob` must be used!
+

+
+### 1.05 Using Variables
+
+**Use Variables to have the path relative**  
+You can use Variables (you should!) to have the path relative!
+
+Writing mostly in Windows with `%windows%` and in Unix with `$unix`... You can use both!
+
+Where to use them: FOLLOWS !!! Not in `.ini`!

+
+<br>
+
+### 1.06 Windows Variables
+
+BleachBit allows all the normal operating system variables, and it adds some extras.  
+Read about the normal operating system variables (Environment Variables):  
+https://en.wikipedia.org/wiki/Environment_variable  
+https://en.wikipedia.org/wiki/Environment_variable#Default_values
+
+Special:  
+Windows itself changes `%ProgramFiles%` for 32-bit processes running in a 64-bit operating system as documented here:  
+https://docs.microsoft.com/en-us/windows/desktop/winprog64/wow64-implementation-details  
+Means, BleachBit shows in "Help - System Information" on 686/x64 systems:  
+os.getenv('ProgramFiles') = C:\Program Files (x86)  
+os.getenv('ProgramW6432') = C:\Program Files  
+...and not:  
+os.getenv('ProgramFiles') = C:\Program Files  
+os.getenv('ProgramW6432') = C:\Program Files
+
+Code for a multi-value variable "ProgramFiles", that should handle this case.  
+Taken from `vuze.xml` from Tobias.  
+For more information about multi-value variables, look into chapter "3.08 Define multi-value Variables".  
+`  <var name="ProgramFiles">`  
+`    <!--`  
+`    Windows itself changes %ProgramFiles% for 32-bit processes running in a 64-bit operating system as documented here:`  
+`    https://docs.microsoft.com/en-us/windows/desktop/winprog64/wow64-implementation-details`  
+`    ...so we used "%SystemDrive%\Program Files\" & "%SystemDrive%\Program Files (x86)\"...`  
+`    <value os="windows">%SystemDrive%\Program Files\[ProgramName]</value>`  
+`    <value os="windows">%SystemDrive%\Program Files (x86)\[ProgramName]</value>`  
+`    ...but %ProgramFiles% & %ProgramFiles(x86)% don't need to be on %SystemDrive% !!!`  
+`    So we use: -->`  
+`    <value os="windows">%ProgramW6432%\Vuze</value>`  
+`    <!-- ...that BleachBit as 32-bit program can find "\Program Files\Vuze" and... -->`  
+`    <value os="windows">%ProgramFiles(x86)%\Vuze</value>`  
+`    <!-- ...that BleachBit can find "\Program Files (x86)\Vuze" and... -->`  
+`    <value os="windows">%ProgramFiles%\Vuze</value>`  
+`    <!-- ...that BleachBit can find "\Program Files\Vuze" on a x86 system...`  
+`    ...and later, as 64-bit program, "\Program Files\Vuze" (x64)!`  
+`    So all cases solved! ;-) Tobias. -->`  
+`    <!--`  
+`    Linux $$ProgramFiles$$ not yet figured out! I will do this later! Tobias.`  
+`    <value os="linux">~/.vuze</value>`  
+`    -->`  
+`  </var>`
+
+Extra Variables:  
+On Windows, BleachBit defines `%cd%` (current directory), `%commonappdata%`, `%documents%`, `%localappdata%` (Windows XP), `%music%`, `%pictures%`, `%video%`, `%localappdatalow%`.
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 1.07 Unix Variables
+
+FOLLOWS !!!
+
+Extra Variables:  
+On Unix, BleachBit defines `$XDG_CONFIG_HOME`, `$XDG_CACHE_HOME`, ...
+For more look here: https://wiki.archlinux.org/index.php/XDG_Base_Directory

+### 1.08 Example Cleaner
+
+Here is an example cleaner:  
+https://github.com/bleachbit/bleachbit/blob/master/doc/example_cleaner.xml
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+<H1>2.00 Header</H1>
+
+<br>
+
+### 2.01 First Line
+
+The first line in a new cleaner file is always `<?xml version="1.0" encoding="UTF-8"?>`.  
+This identifies the file as a XML file.  
+CleanerML files are a special version of XML files.
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 2.02 Copyright & Additional Information
+
+Your cleaners should retain the copyright and information header found in `release/*.xml`. Please edit the copyright information accordingly.  
+If needed, you can also include extra maintenance information in the header, as found in [release/openshot.xml](https://github.com/az0/cleanerml/blob/master/openshot.xml):
+
+    @url http://full.url.of/software-project
+    @tested ok softwareversion, OSnameandversion
+    @note Some notes for cleaner maintainers
+
+**Example for a other version:**
+
+    @app Double Commander
+    @url https://doublecmd.sourceforge.io/
+    @os Windows, Linux, FreeBSD
+    @cleanerversion v0.2.5
+    @cleanerdate 2019-03-11

+
+### 2.03 Cleaner Element & ID
+
+The cleaner starts with the `<cleaner>` element.  
+Example for a `<cleaner>` header: `<cleaner id="smplayer">`  
+`id` is the BleachBit internal ID of the cleaner.
+
+`<cleaner>` can define that the cleaner is OS dependent.  
+For more information to this look at: OS dependent parts/cleaners
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+<H1>3.00 General Structure & Configurations per Cleaner</H1>
+
+<br>
+
+### 3.01 Label Element
+
+After that comes `<label>`.  
+`<label>` defines the label shown as name (of the cleaner) in the left column of BleachBit.  
+Example: `<label>SMPlayer</label>`
+
+`<label>` can have some attributes...
+
+Example: `<label translate="true">Deep Scan - More</label>`  
+If the label should be translated by the translators into local.
+
+Example: `<label translators="In Windows 'Run' is the dialog in the Start menu">Run</label>`  
+As note for the translators.
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.02 Description Element
+
+And then we need a description of the cleaner (this time a category!) (shown on the right side of BleachBit).  
+Example of a `<description>` element: `<description>Video player</description>`
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.03 Option Element
+
+Then comes the first `<option>` and then for the `<option>` a `<label>` and a `<description>` (this time a explanaition!), again.  
+Example:  
+`<cleaner id="tomtom" os="windows">`  
+`  <label>TomTom</label>`  
+`  <description>Navigation systems</description>`  
+`  <option id="cookies">`  
+`    <label>Cookies</label>`  
+`    <description>Delete cookies, which contain information such as web site preferences, authentication, and tracking identification</description>`
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.04 More pretty (Label, Option & Description)
+
+Please use (if possible) terms for `<label>`s of `<option>`s and `<description>`s (for `<cleaner>` and `<option>`), that are already used somewhere else in the program!
+This makes translation easier, because the term can be maybe be already translated! E.g. don't use "Temp files" or "Temporary Files", use "Temporary files"! (Yes, it is case sensetive!)  
+Example:  
+`<label>Temporary files</label>`  
+`<description>Delete the temporary files</description>`
+
+Use the writing/naming form, that is used by the other cleaners/options, too!  
+Example: Don't write "Junk Files", use "Junk files"! (Yes, it is case sensetive!)
+
+We make no dot at the end of `<description>`!
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.05 Running Element
+
+With `running type="exe"` you can prevent that the cleaner gets executed as long a special program/task is running...  
+Example: `<running type="exe" os="windows">firefox.exe</running>`
+
+With `running type="pathname"` you can also prevent that the cleaner gets executed, but as long as a special file exist!  
+Example: `<running type="pathname">~/.mozilla/firefox/*.default/lock</running>`
+
+Generally it is preffered to have this exe/pathname check included in cleaners!  
+And generally the `exe` variation is preffered over the `pathname` variation!
+
+Btw.: `running` need no `search="glob"`, because `running` is always `glob`!
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.06 OS dependent parts/Cleaners
+
+**Make a part, or the cleaner OS dependent**  
+You can make the cleaner (a part, or the hole cleaner) OS dependent by adding the `os=` attribute.
+
+**Example:**  
+`<cleaner id="windows" os="windows">`
+
+**Explanaition:**  
+Adding the `os=` attribute in the `<cleaner>` element makes the cleaner OS dependent and boosts load time of BleachBit.  
+Version 2.1 of BleachBit adds support for `os=` on the elements `action`, `value`, and `running`.  
+For `os` can be used `windows`, `linux`, `FreeBSD`, `NetBSD`, `OpenBSD` & `unix`. While `os="unix"` includes Linux, the three BSD systems, and Darwin.
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.07 Display a Warning
+
+**Display a warning to the user**  
+Displays a warning to the user if the cleaner gets selected in BleachBit.
+
+**Example:**  
+`<warning>Use the option only if you know what you do!</warning>`
+
+**Explanaition:**  
+`<warning>` gets used inside the `<option>` section, on top, as first rule.
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 3.08 Define multi-value Variables
+
+**A cleaner can have multiple variables**  
+You can define one or more variables in a cleaner with `<var>` and `<value>`.
+
+**Example:**  
+`<var name="profile">`  
+`  <value os="windows">%USERPROFILE%\.smplayer</value>`  
+`  <value os="linux">~/.config/smplayer</value>`  
+`</var>`
+
+**Explanaition:**  
+Defines with `<var>` the variable "profile" that is after that definded with `<value>` for `os="windows"` and `os="linux"`.
+
+MORE FOLLOWS !!!
+
+Variable syntax: $$multi$$
+
+**Example with two values for one OS:**  
+`<var name="profile">  
+`  <value os="windows">%LocalAppData%\Google\Chrome\User Data\Default</value>`  
+`  <value os="linux">$XDG_CONFIG_HOME/google-chrome/Default</value>`  
+`  <value os="linux">$XDG_CONFIG_HOME/google-chrome-beta/Default</value>`  
+`</var>`
+
+**Example for a value, when the path includes a "*":**  
+`<value search="glob" os="windows">%AppData%\Mozilla\Firefox\Profiles\*</value>`

+<H1>4.00 command="delete"</H1>
+
+<br>
+
+### 4.01 command="delete" search="file"
+
+**Deleting a single file/or an empty folder**  
+Deletes a single file or an empty folder in the file system.
+
+**Example:**  
+`<action command="delete" search="file" path="$APPDATA\XnView\XnView.db"`
+
+**Explanaition:**  
+`command` is always `"delete"`, `search` is always `"file"`, `path` is the path & name of the file to delete.
+
+`<action command="delete" search="file" path="%ProgramFiles%\BiglyBT\*.log"/>`  
+**Doesn't work! No wildcards allowed (, yet)!**  
+**Use `glob`!**  
+
+`<action command="delete" search="file" path="%ProgramFiles%\BiglyBT*\test.log"/>`  
+**Doesn't work! No wildcards allowed (, yet)!**  
+**Use `glob`!**  
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 4.02 command="delete" search="walk.files"
+
+**Follows**  
+Follows
+
+**Example:**  
+Follows
+
+**Explanaition:**  
+Follows
+
+`<action command="delete" search="walk.files" path="%ProgramFiles%\BiglyBT\*.log"/>`  
+**Doesn't work! No wildcards allowed (, yet)!**  
+**Use `glob`!**  
+
+`<action command="delete" search="walk.files" path="%ProgramFiles%\BiglyBT*\test.log"/>`  
+**Doesn't work! No wildcards allowed (, yet)!**  
+**Use `glob`!**  
+
+`<action command="delete" search="walk.files" path="%ProgramData%\Microsoft\Search\Data\Applications\Windows\GatherLogs\SystemIndex\*"/>`  
+**Doesn't work! No `*` at the end allowed (, yet)!**  
+**Use `glob`!**  
+
+`<action command="delete" search="walk.files" path="%AppData%\Daum\PotPlayer\Log\*"/>`  
+If you mean every directory under %AppData%\Daum\PotPlayer\Log\, then walk.files is right, but if you want every file then you want either `search="glob"` (which will not delete recursively) OR remove the wildcard (which will delete recursively)!
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 4.03 command="delete" search="walk.all"
+
+**Follows**  
+Delete e.g. the content of a folder.
+
+**Example:**  
+Follows
+
+**Explanaition:**  
+Follows ... walk.all is intended to match directories, not files.
+
+If you add a "*" at the end of a path by `walk.all`, the content of the folder doesn't get deleted!  
+`<action command="delete" search="walk.all" path="%windir%\Temp\*"/>`
+Explanaition: The "*" is a wildcard for a folder - so the content in the subfolders get deleted!
+
+And this doesn't work, too.  
+`<action command="delete" search="walk.all" path="%windir%\Temp\WER*.hdmp"/>`  
+Use `glob` instead:  
+`<action command="delete" search="glob" path="%windir%\Temp\WER*.hdmp"/>`
+
+This also doesn't work!  
+`<action command="delete" search="walk.all" path="%windir%\Temp*\WER1.hdmp"/>`  
+Use `glob` instead:  
+`<action command="delete" search="glob" path="%windir%\Temp*\WER1.hdmp"/>`
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 4.04 command="delete" search="walk.top"
+
+**Deleting a single folder**  
+Deletes a single folder including his content in the file system.  
+**This feature is implemented starting with BleachBit v3.0!**  
+**As some users still stay on Windows XP with BleachBit v2.2 (last version for WinXP) but use new cleaners,  
+it is highly recommended to use this new feature at the moment with care!**
+
+**Example:**  
+`<action command="delete" search="walk.top" path="%Temp%\DemoFolder\"`
+
+**Explanaition:**  
+`command` is always `"delete"`, `search` is always `"walk.top"`, `path` is the path & name of the folder to delete.
+
+**More Examples:**  
+`<action command="delete" search="walk.top" path="%ProgramFiles%\BiglyBT*\"/>` will delete in `%ProgramFiles%`  
+all folders starting with `BiglyBT*`.  
+
+[Back to index](#content-of-the-chapter)
+
+<br>
+
+### 4.05 command="delete" search="glob"
+
+**Follows**  
+Needed if you e.g. use a wildcard (`*`)!  
+**Wherever a glob pattern is supporter, there is no practical limit on the number of wildcards.**
+
+**Example:**  
+`<action command="delete" search="glob" path="%windir%\Temp\WER*.hdmp"/>`
+
+**Explanaition:**

+
+**You can delete the content of a folder and not the folder itself**  
+Follows
+
+**Example:**  
+`<action command="delete" search="walk.all" path="$LocalAppData\Temp\acrord32_sbx"/>`  
+`<action command="delete" search="glob" path="$LocalAppData\Temp\acrord32_sbx\*"/>`
+
+**Explanaition:**  
+`walk.all` deletes the content of the folder and shows it in BleachBit, while `glob` with a `\` at the end of `path` deletes the folders in the folder.

+### 4.07 Delete the content of a folder and the folder itself
+
+**You can delete the content of a folder and the folder itself**  
+Follows
+
+**Example:**  
+`<action command="delete" search="walk.all" path="$LocalAppData\Temp\acrord32_sbx"/>`  
+`<action command="delete" search="file" path="$LocalAppData\Temp\acrord32_sbx"/>`
+
+**Explanaition:**  
+`walk.all` deletes the content of the folder and shows it in BleachBit, while `file` deletes after that the empty folder itself.
+
+**Starting with BleachBit v3.0 there is `command="delete" search="walk.top"` as a single command to do that!  
+But as some users still stay on Windows XP with BleachBit v2.2 (last version for WinXP) but use new cleaners,  
+it is highly recommended to use this new feature at the moment with care!**

+
+**Follows**  
+Follows
+
+**Example:**  
+`<action command="delete" search="walk.files" path="$$profile$$\" regex="\.[Bb][Aa][Kk]$"/>`
+
+**Explanaition:**  
+Follows
+
+**More examples:**  
+`regex="\.[Bb][Aa][Kk]$"` -> File Extension, not key sensetive  
+`regex="^Thumbs\.db$"` -> Exact file name  
+`regex="^`[...] -> File name starts with  
+`regex="\.`[...] -> File extension is  
+`regex="\.log(\.[0-9]+)?$` -> File extension is `.log.[0-9]` + The plus will match one or more such as 1 or 99 and the question mark makes the number optional  
+Test the logic of your regex string: https://regex101.com/
+
+Works also with `walk.all` & `glob` (`file` too, but makes no sence)!

+### 4.09 command="delete" search="deep"
+
+**Follows**  
+`command="delete" search="deep"` searches across the file system, currently just the user profile, and it is optimized for speed to search for multiple patterns at once.
+
+**Example:**  
+`<action command="delete" search="deep" cache="false" regex="\.[Ll][Oo][Gg]$"/>`
+
+**Explanaition:**  
+Follows
+
+**More examples:**  
+For more `regex` examples look one chapter above under "Delete recursive with regex"!
+
+If you find in a cleaner a `search="deep"` with a `cache="false"` (or a `cache="true"`), then you can delete the `cache="false"` (or `cache="true"`)!
+This feature was never fully implemented and later removed, again!
