First, let's take a look at the functions of tag signing:
Tags are used to identify the current version status of the entire product;
Each file in CVS has its own version number, but the entire product should also have a version ID (such as Alpha, beta, and official release ), so how do we know the version of each file contained in the beta version of the product? The tag name is generally the version ID of the product. The tag shows the files and versions of each file.
Generally, you need to tag the product version when releasing it, whether it is used to build an internal test environment or release it externally.
Next, let's take a look at how to tag in CVS:
To tag one or more files or directories, follow these steps:
1) Right-click the directory or file you want to tag and select CVS/Tag
2) In the displayed dialog box, select "create new tag" and enter the tag name in the tag name input box.
3) Click OK. After the tag is created, the tag is added to the current version of all files in the folder.
