ignore - ignore the example, useful for examples that just use the syntax highlighting
failcompile - known failing compilation. Useful for examples demonstrating compiler errors.
oksyntax - it should parse, it may not compile. Useful for partial examples.
badsyntax - known bad syntax, it should not even parse
wip - like ignore; a planned feature; easy to search.

check-md is a tool to check the passed markdown files for correct ```v ``` code blocks
and other style violations like too long lines/links etc...
Usage:
a) `v check-md [flags] <...files>` - Check the given .md files.
b) `v check-md [flags] <...dirs>` - Check *all* files in the given directories.
Note: You can also combine files and directories.
Flags:
-hide-warnings Do not print warnings, only errors.
NB: There are several special keywords, which you can put after the code fences for v.
These are:
compile - Default, can be omitted. The example will be compiled and formatting is verified.
live - Compile hot reload examples with the ´-live´ flag set and verify formatting.
ignore - Ignore the example, useful for examples that just use the syntax highlighting
failcompile - Known failing compilation. Useful for examples demonstrating compiler errors.
oksyntax - Should parse and be formatted but may not compile. Useful for partial examples.
badsyntax - Known bad syntax, it should not even parse.
wip - Like ignore; a planned feature; easy to search.
nofmt - Disable fmt verification for individual code blocks.

because it tries to also verify that `v install` works.
