Schema generator CLI usage
==========================
```sh
dbschemagen -d mysql -s test_db -z 1e9 -t 5 -- --escape-backslash > gen.sh
sh gen.sh
```
Common options
--------------
* `-d «DIALECT»`, `--dialect «DIALECT»`
Choose the SQL dialect of the generated schema files. This mainly controls the data type names.
* `-s «NAME»`, `--schema-name «NAME»`
The qualified schema name.
* `-z «SIZE»`, `--size «SIZE»`
The estimated total size of the generated data file.
* `-t «N»`, `--tables-count «N»`
Number of tables to generate.
Note that `dbschemagen` will *not* uniformly distribute the same size to every file; rather,
they're assigned following to Lomax distribution to simulate the size of real-world databases.
* `-- «args»...`
Any extra arguments will be passed to the `dbgen` invocations.
More options
------------
* `-n «N»`, `--inserts-count «N»`
Number of INSERT statements per file.
* `-r «N»`, `--rows-count «N»`
Number of rows per INSERT statement.
* `--seed «SEED»`
Provide a 64-digit hex number to seed the random number generator, so that the output becomes
reproducible. If not specified, the seed will be obtained from the system entropy.
(Note: There is no guarantee that the same seed will produce the same output across major
versions of `dbschemagen`.)
