-### PEAR
-
-It is possible to install packages from any PEAR channel by using the `pear`
-repository. Composer will prefix all package names with `pear-{channelName}/`
-to avoid conflicts. All packages are also aliased with prefix
-`pear-{channelAlias}/`.
-
-Example using `pear2.php.net`:
-
-```json
-{
-    "repositories": [
-        {
-            "type": "pear",
-            "url": "https://pear2.php.net"
-        }
-    ],
-    "require": {
-        "pear-pear2.php.net/PEAR2_Text_Markdown": "*",
-        "pear-pear2/PEAR2_HTTP_Request": "*"
-    }
-}
-```
-
-In this case the short name of the channel is `pear2`, so the
-`PEAR2_HTTP_Request` package name becomes `pear-pear2/PEAR2_HTTP_Request`.
-
-> **Note:** The `pear` repository requires doing quite a few requests per
-> package, so this may considerably slow down the installation process.
-
-#### Custom vendor alias
-
-It is possible to alias PEAR channel packages with a custom vendor name.
-
-Example:
-
-Suppose you have a private PEAR repository and wish to use Composer to
-incorporate dependencies from a VCS. Your PEAR repository contains the
-following packages:
-
- * `BasePackage`
- * `IntermediatePackage`, which depends on `BasePackage`
- * `TopLevelPackage1` and `TopLevelPackage2` which both depend
-    on `IntermediatePackage`
-
-Without a vendor alias, Composer will use the PEAR channel name as the
-vendor portion of the package name:
-
- * `pear-pear.foobar.repo/BasePackage`
- * `pear-pear.foobar.repo/IntermediatePackage`
- * `pear-pear.foobar.repo/TopLevelPackage1`
- * `pear-pear.foobar.repo/TopLevelPackage2`
-
-Suppose at a later time you wish to migrate your PEAR packages to a
-Composer repository and naming scheme, and adopt the vendor name of `foobar`.
-Projects using your PEAR packages would not see the updated packages, since
-they have a different vendor name (`foobar/IntermediatePackage` vs
-`pear-pear.foobar.repo/IntermediatePackage`).
-
-By specifying `vendor-alias` for the PEAR repository from the start, you can
-avoid this scenario and future-proof your package names.
-
-To illustrate, the following example would get the `BasePackage`,
-`TopLevelPackage1`, and `TopLevelPackage2` packages from your PEAR repository
-and `IntermediatePackage` from a Github repository:
-
-```json
-{
-    "repositories": [
-        {
-            "type": "git",
-            "url": "https://github.com/foobar/intermediate.git"
-        },
-        {
-            "type": "pear",
-            "url": "http://pear.foobar.repo",
-            "vendor-alias": "foobar"
-        }
-    ],
-    "require": {
-        "foobar/TopLevelPackage1": "*",
-        "foobar/TopLevelPackage2": "*"
-    }
-}
-```

-            <s>database abstraction layer</s>
-            <d>PEAR MDB2 is a merge of the PEAR DB and Metabase php database abstraction layers.
-
-                It provides a common API for all supported RDBMS. The main difference to most
-                other DB abstraction packages is that MDB2 goes much further to ensure
-                portability. MDB2 provides most of its many features optionally that
-                can be used to construct portable SQL statements:
-                * Object-Oriented API
-                * A DSN (data source name) or array format for specifying database servers
-                * Datatype abstraction and on demand datatype conversion
-                * Various optional fetch modes to fix portability issues
-                * Portable error codes
-                * Sequential and non sequential row fetching as well as bulk fetching
-                * Ability to make buffered and unbuffered queries
-                * Ordered array and associative array for the fetched rows
-                * Prepare/execute (bind) named and unnamed placeholder emulation
-                * Sequence/autoincrement emulation
-                * Replace emulation
-                * Limited sub select emulation
-                * Row limit emulation
-                * Transactions/savepoint support
-                * Large Object support
-                * Index/Unique Key/Primary Key support
-                * Pattern matching abstraction
-                * Module framework to load advanced functionality on demand
-                * Ability to read the information schema
-                * RDBMS management methods (creating, dropping, altering)
-                * Reverse engineering schemas from an existing database
-                * SQL function call abstraction
-                * Full integration into the PEAR Framework
-                * PHPDoc API documentation</d>
