/* checkTag : validation tool for libzstd
|
|
* command :
|
|
* $ ./checkTag tag
|
|
* checkTag validates tags of following format : v[0-9].[0-9].[0-9]{any}
|
|
* The tag is then compared to zstd version number.
|
|
* They are compatible if first 3 digits are identical.
|
|
* Anything beyond that is free, and doesn't impact validation.
|
|
* Example : tag v1.8.1.2 is compatible with version 1.8.1
|
|
* When tag and version are not compatible, program exits with error code 1.
|
|
* When they are compatible, it exists with a code 0.
|
|
* checkTag is intended to be used in automated testing environment.
