Convert the README to Markdown

Shithub decided not to render symlinked pod files sometime in the past
year (github/markup#1253) so let's add a Markdown version generated by
pod2markdown.

+# NAME
+
+ldm - Lightweight Device Mounter
+
+# SYNOPSIS
+
+_ldm_ \[-d\] \[-u _user_\] \[-p _path_\] \[-c _command_\] \[-m _mask_\] \[-h\]
+
+# DESCRIPTION
+
+ldm is a lightweight device mounter following the UNIX philosophy written in C and based on udev and libmount.
+The user can use **umount** to unmount the device or **ldmc** with the **-r** switch.
+The daemon can be controlled with the **ldmc** tool.
+
+# OPTIONS
+
+- **-d**
+
+    Run ldm as a daemon.
+
+- **-u** _user_
+
+    Specify the user who owns the mountpoints.
+
+- **-p** _path_
+
+    Specify the base folder for the mount points. The default is /mnt.
+
+- **-m** _fmask_,_dmask_
+
+    Specify the fmask and dmask for the mounted devices in octal or symbolic format (eg. the octal mask
+    0777 is represented as rwxrwxrwx).
+
+    If only the _fmask_ is specified then its used as umask and it's
+    value is used as dmask too.
+
+- **-c** _command_
+
+    Specifies a command that is executed after a successful mount/unmount action. The following environment variables are defined :
+
+    - **LDM\_MOUNTPOINT**
+
+        The complete path to the mountpoint.
+
+    - **LDM\_NODE**
+
+        The path pointing to the device node in /dev
+
+    - **LDM\_FS**
+
+        The filesystem on the mounted device.
+
+    - **LDM\_ACTION**
+
+        The action ldm has just performed, it can either be _mount_, _pre\_unmount_ or _unmount_
+
+- **-h**
+
+    Print a brief help and exit.
+
+# BLACKLISTING
+
+ldm doesn't offer any blacklisting by itself but it honors the options found in the fstab so it will ignore any device with flag _noauto_.
+
+# INSTALL
+
+The included systemd service expects a config file at /etc/ldm.conf similar to this:
+
+<div>
+    <pre>
+    <code>
+    MOUNT_OWNER=<i>username</i>
+    BASE_MOUNTPOINT=<i>/mnt</i>
+    FMASK_DMASK=<i>fmask,dmask</i>
+    EXTRA_ARGS=<i>-c &lt;path_to_executable&gt;</i>
+    </code>
+    </pre>
+</div>
+
+The options **FMASK\_DMASK** and **EXTRA\_ARGS** are optional.
+The default value for **FMASK\_DMASK** is _0133,0022_.
+**EXTRA\_ARGS** will be appended to the _ldm_ executable.
