= Installed Directory Layout =

Typically the OSGeo4W tree is installed in C:\OSGeo4W but it is permitted to be located anywhere on the system.  All paths below are relative to the user selected root directory.
 
 * /apache: the Apache web server
 * /apache/htdocs: The web document directory.  Web applications should only include a .pkg file in this directory, see the "Web Application Package Guidelines" section below for more information.
 * /apps: Directory for applications that need their own directory tree, and don't fit conveniently into /bin, /lib, etc.  Each app appearing here should have a subdirectory with a name closely related to the name of the package. 
 * /bin: most .exe and .dll files intended to be in the user path.  The apache alias '/cgi-bin/' also points to this /bin directory.
 * /etc/ini: .bat files to be called from OSGEO4W_ROOT/osgeo4w.bat - usually these contain SET statements for required environment variables.
 * /etc/postinstall: per package post-install scripts
 * /etc/setup: used by cygwin setup to keep track of installed packages. 
 * /http.d: apache configuration files, one per package. See the "Web Application Package Guidelines" section below for more information. 
 * /include: include files required for building additional packages and executables.
 * /lib: static and stub libraries required for building additional packages and executables.
 * /share: static support data files.
 * /src: When available source packages should unpack here with a directory name matching the package name. 
 * /tmp - directory to store temporary files (non-web-accessible)
 * /tmp/ms_tmp/ directory to store temporary web-accessible files 
 * /var: currently used by Cygwin setup.exe
