| Apache JDO Documentation Template |
| ================================== |
| This template derived various aspects from Apache Deltaspike template, the Apache ISIS template and the Datanucleus template. |
| This template uses |
| * Bootstrap v3.3.7 (https://getbootstrap.com/) for navbar. |
| * Asciidoctor "foundation" CSS |
| * Bootswatch "cosmo" theme for Bootstrap (https://bootswatch.com/cosmo). |
| * Bootstrap TOC plugin v0.4.1 (https://afeld.github.io/bootstrap-toc/) for the table of contents. |
| * jQuery (necessary for Bootstrap's JavaScript plugins) |
| * Font-Awesome for some icons used by Asciidoctor |
| NOTE: tried using Font-Awesome CSS hosted locally but then fails to work! |

| <p>If you use Subversion on Windows under cygwin, you may find that the |
| Subversion client automatically assigns the executable property to |
| non-executable files. In that case, you would see this at the bottom of |
| an <em>svn diff</em> of the file:</p> |

| <p>Subversion carries executable information in the built-in property |
| called svn:executable. This property, unlike others, may be present or |
| absent, but it has no value. You can add it or delete it, but but you |
| cannot change its value.</p> |
| </div> |
| <div class="paragraph"> |
| <p>In theory, Subversion ignores Windows file permissions and by default |
| does not set svn:executable. However, cygwin svn acts like Unix svn and |
| determines the svn:executable property based on file permissions.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If you create a file from the cygwin command line, by default it is |
| executable only if the filename ends with .bat, .com or .exe, or if its |
| content starts with #!. [This is what the doc says, but you may see -x |
| for all files.] If you create a file using a Windows tool, by default |
| its Windows permissions are executable by all. Cygwin interprets the |
| Unix-style permissions this way as well. If the file is executable by |
| all, cygwin svn sets the svn:executable property on the file when you |
| invoke <em>svn add</em>.</p> |

| <p>Windows/cygwin users who don’t want to have to think about using <em>svn |
| propdel</em> or <em>chmod</em> on each added file can use a non-cygwin version of |
| svn. The Subversion 1.2.3 Win32 binaries, downloadable from the link at |
| the bottom of <a href="http://subversion.tigris.org/project_packages.html" class="bare">http://subversion.tigris.org/project_packages.html</a>, appear |
| to work well. After installation add the svn.exe location to your |
| Windows PATH variable. If you are switching from cygwin svn to Win32 svn</p> |

| <div class="olist arabic"> |
| <ol class="arabic"> |
| <li> |
| <p>Remove the subversion component from your cygwin installation because |
| when svn is invoked from a cygwin window, the cygwin version is found |
| even if your cygwin/bin directory is later on the path. (In the Select |
| Packages window of the setup wizard, navigate to the subversion package |
| in the Devel. category. Click on the status icon until Uninstall is |
| displayed. Click next and continue through the wizard until installation |
| is complete.)</p> |
| </li> |
| <li> |
| <p>Copy the servers file and the auth folder from the sygwin |
| ~/.subversion directory to C:\Documents and Settings\<user>\Application |
| Data\Subversion used by Win32 subversion.</p> |
| </li> |
| </ol> |
| </div> |
| <div class="paragraph"> |
| <p>Note that windows svn uses backslash as the path separator when |
| displaying file names. You cannot just copy and paste this file name to |
| another svn command when running from within a cygwin shell. You need to |
| enclose the file name into double quotes.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Alternatively, Windows users can set file permissions in Windows |
| Explorer. (Right-click on the top-level folder & select Properties. |
| Select the Security tab. Click Advanced. Remove all instances of Read & |
| Execute from the Permission Entries. Click "Reset permissions on all |
| child objects and enable propogations of inheritable permissions". Click |
| Apply. OK. OK.) You will have to do this again when you do a clean |
| checkout to a new directory.</p> |
