+## Advantages
+
+> ### Cross libc
+> +0-15% performance, depending on the application  
+> packages use the most appropriate libc library
+> ### Profile-guided optimization
+> +5-20% performance, optimization for any usage scenario  
+> (to use in build set pgo=true in env)
+
+## Flexibility
+> ### Simple insulation
+> At the repository level  
+> Packages with completely incompatible libraries are separated into different repositories:  
+> /pkg/\<repo\>  
+>  
+> Between the packages  
+> Packages are installed as "packages" in different folders:  
+> /pkg/\<repo\>/\<pkgname\>  
+>  
+> The repository combines files /pkg/\<repo\>/\<pkgname\>/{bin, lib, ...} to /pkg/\<repo\>/{bin, lib, ...}  
+> ### Storage optimization
+> Final Assembly Philosophy:  
+> After the final system build, when no more packages need to be installed.  
+> Flexible removal of all unused files by reading time  
+## Easy to use
+> Isolating packages makes it easy to find a configuration  
+> `pkg config \<pkgname\>` squirrel makes it even easier
