+- Variables must appear at the top of each file.
+- Types must appear after variables.
+- Constructors must appear after types.
+- Public (exported) functions must appear after constructors.
+- Private (unexported) functions must appear at the bottom of each file.
+- Within each section, definitions must be sorted alphabetically by name.

+Keep Go lines as short as reasonably possible.

+- **Hard limit:** 120 characters — never exceed this.
+- **Preferred:** 100 characters or fewer in normal cases.
+- **Target:** 80 characters if breaking the line produces cleaner, more readable

+# Checking if a Package is Provided by Another Package
+
+## Using FindDBSatisfier
+
+The `FindDBSatisfier` method in the handle finds a package that satisfies a given dependency string across sync databases. It automatically resolves `Provides` relationships.
+
+### Basic Usage
+
+```go
+// Given a package name "foo", find which package provides it
+h := dyalpm.NewHandle(...)
+dbs := h.SyncDBS()
+
+// This finds ANY package that satisfies "foo" - including via Provides
+provider := h.FindDBSatisfier(dbs, "foo")
+if provider != nil {
+    // The package "foo" is provided by provider.Name()
+}
+```
+
+### How It Works
+
+When you search for a package "foo", ALPM will find packages that:
+1. Are named "foo"
+2. Have `Provides: foo` in their metadata
+
+### Full Example
+
+```go
+h, err := dyalpm.NewHandle(rootDir, cacheDir, dyalpm.ArchLinux)
+if err != nil {
+    // handle error
+}
+
+syncDBs, err := h.SyncDBS()
+if err != nil {
+    // handle error
+}
+
+// Search for "foo" package (may be provided by another package)
+targetName := "foo"
+provider := h.FindDBSatisfier(syncDBs, targetName)
+
+if provider != nil {
+    fmt.Printf("%s is provided by: %s\n", targetName, provider.Name())
+    fmt.Printf("Version: %s\n", provider.Version())
+} else {
+    fmt.Printf("No package found providing: %s\n", targetName)
+}
+```
+
+## Related Functions
+
+- `FindSatisfier(pkgs []Package, depstring)` - Same concept but for an in-memory package list
+- `PackageIterator.FindSatisfier(depstring)` - Works on iterator results from `db.Search()`
+- `pkg.Provides() []Depend` - Get what a package provides (see `package.go:144`)
