One possible method to obtain package description in Delphi prior to loading it at runtime is by utilizing the TPackageInfo record, which can be queried using the GetPackageInfo function from the System.SysUtils unit.

Here is an example code snippet:


  TMyPackageInfo = record
    Name: string;
    Description: string;

function GetPackageDescription(const PackageName: string): string;
  PkgInfo: TPackageInfo;
  if GetPackageInfo(PChar(PackageName), @PkgInfo) <> nil then
    Result := PkgInfo.Description
    Result := '';

In this example, the GetPackageDescription function takes a package name as parameter and returns its description if available. This is achieved by calling the GetPackageInfo function passing the package name and a pointer to a TPackageInfo structure. If the function returns a non-nil pointer, the description is extracted and returned as result. Otherwise, an empty string is returned.

Note that this is just one possible approach and may not work for all packages or Delphi versions. Additionally, it's worth noting that obtaining package information at runtime may have performance implications and should be used with caution.
