Any path seperators must be # UNIX style forward slashes '/', even on Windows. # # This configuration file is not intended to be modified by the user. Doing so # may cause the product to become unstable or unusable. If options need to be # modified or added, the user may do so by modifying the custom configuration files # located in the user's home directory. The location of these files is dependent # on the product name and host platform, but may be found according to the # following guidelines: # # Windows Platforms: # The location of user/product files are often configured during installation, # but may be found in: # %APPDATA%\\\\\\product.conf # %APPDATA%\\\\\\jdev.conf # # Unix/Linux/Mac/Solaris: # $HOME/.//product.conf # $HOME/.//jdev.conf # # In particular, the directives to set the initial and maximum Java memory # and the SetJavaHome directive to specify the JDK location can be overridden # in that file instead of modifying this file. \`\`\`
