+Skip part of a file.

+
+As `head` will show the top of a file after a number of line,
+ so `skip` will do the opposite, and not show the top of the file,
+ but will show the rest.
+
+Additionally, it can check for whole lines matching,
+ or for a token being present on the line.
+
+## Usage
+
+### Skip a fixed number of lines
+
+This example reads the file from stdin.
+
+File: `input.txt`
+
+```text
+line 1
+line 2
+line 3
+line 4
+```
+
+```bash
+skip 2 < input.txt
+```
+
+Will output:
+
+```text
+line 3
+line 4
+```
+
+### Skip until a number of matching lines
+
+This example reads the named file.
+
+File: `input.txt`
+
+```text
+alpha
+beta
+alpha
+alpha
+gamma
+alpha
+```
+
+```bash
+skip 2 --line alpha input.txt
+```
+
+Will output:
+
+```text
+alpha
+gamma
+alpha
+```
+
+### Skip lines until a number of tokens as seen
+
+This example reads the file from stdin.
+
+File: `input.txt`
+
+```text
+Lorem ipsum dolor sit amet, 
+consectetur adipiscing elit, 
+sed do eiusmod tempor incididunt 
+ut labore et dolore magna aliqua. 
+Ut enim ad minim veniam, 
+quis nostrud exercitation ullamco 
+laboris nisi ut aliquip ex ea 
+commodo consequat. 
+```
+
+```bash
+cat input.txt | skip 2 --token dolor
+```
+
+Will output:
+
+```text
+Ut enim ad minim veniam, 
+quis nostrud exercitation ullamco 
+laboris nisi ut aliquip ex ea 
+commodo consequat. 
+```
+
+It matches the first `dolor` on line 1,
+ and the second on line 4 as part of the word `dolore`.
