{- Generates a NullSoft installer program for git-annex on Windows.
|
|
-
|
|
- To build the installer, git-annex should already be built by cabal,
|
|
- and ssh and rsync etc, as well as cygwin libraries, already installed
|
|
- from cygwin.
|
|
-
|
|
- This uses the Haskell nsis package (cabal install nsis)
|
|
- to generate a .nsi file, which is then used to produce
|
|
- git-annex-installer.exe
|
|
-
|
|
- The installer includes git-annex, and utilities it uses, with the
|
|
- exception of git. The user needs to install git separately,
|
|
- and the installer checks for that.
