-= pkgsrc patches =
+This repository contains my patches for various pkgsrc packages as
+well as the NetBSD distribution itself. It also contains scripts
+that make it easier to write patches.
 
-== Modifying a package ==
+The pkg* scripts are designed to be used in conjunction with the
+scripts from the pkgtools/pkgdiff package, as they depend on the
+existence of .orig files.
 
-	cd /usr/pkgsrc/path-to/package
-	make fetch
-	cd /usr/pkgsrc/distfiles
-	tar xf archived-package.tgz
-	cd extracted-package/
+   Use `pkgdiffs' to make a patch containing multiple changes.
+   Use `pkgpatch' to apply a patch to a source directory.
+   Use `pkgundo' to reinstate the original files.
 
-At this point, you can either decide to track your changes by
-initializing a Git repository
+The other scripts have no special relation to pkgtools/pkgdiff.
 
-	git init
-	git commit .
+   Use `convpatch' to make a patch from `git diff' output.
+   Use `savepatch' to save a patch in ~/patches.
+   Use `undopatch' to undo all patches applied to a pkgsrc build.
+   Use `xpkg' to fetch and extract a pkgsrc package.
 
-or by using pkgvi and pkgdiff:
+The `undopatch' and `xpkg' scripts are only to be used within pkgsrc
+package directories. They do nothing within the NetBSD source tree.
 
-	pkgvi file.c
-	pkgdiff file.c > ~/patches/path-to/package/patch-name

-== Generating a patch from Git ==
+To have `make do-patch' apply local patches, be sure to set the
+LOCALPATCHES variable in mk.conf:
 
-	cd /path-to/extracted-package/
-	git diff ... | conv -i
+	echo LOCALPATCHES = ~/patches >> /etc/mk.conf
 
-The resulting patch will be placed in ~/patches.
-
-== Applying a patch ==
-
-Be sure to set the LOCALPATCHES variable in mk.conf:
-
-	echo LOCALPATCHES = $HOME/patches >> /etc/mk.conf
-
-After that, local patches will be applied automatically, assuming
-they are formatted correctly and placed in the correct directory.
-
-== Undoing patches ==
-
-In order to undo all patches, you need to extract the original
-files from the downloaded archive.
-
-	cd /usr/pkgsrc/path-to/package
-	w=/usr/pkgsrc/distfiles/$(sed -n '/.*(\(.*\)).*/{s//\1/;p;q}' distinfo)
-	cd $(dirname $w)
-	tar xf $w
-	cd -
-	find . -name '*.orig' | while read f; do
-		f=${f%.orig}
-		cp $w/${f#./work/} $f
-	done
-
-It is not reliable to restore the original files using the .orig
-files, as multiple patches may have been applied to the same file.
-
-You can use the undopatch script to automate this.
-
-== Rebuilding with new patch ==
+To rebuild a package with new patches, something along the following
+lines should be performed:
 
 	undopatch
 	make do-patch
