We list all known projects using APR at + http://apr.apache.org/projects.html -- so please let us know + if you find our libraries useful in your own projects! + + +Database Providers +------------------ +As of apr-util version 1.2.11, MySQL DBD driver is shipped as part of the +distribution. However, to avoid licensing incompatibilities, it is not +built by default. To enable MySQL support, use the --with-mysql option, +but be aware that the MySQL license may introduce licensing implications +for your compiled code. Similarly, the bindings for propritary drivers +such as Oracle (--with-oracle option) must also be explicitly enabled. + +On windows, selection of supported drivers is via the environment values +DBD_LIST (for freetds, mysql, oracle, pgsql, sqlite2 and/or sqlite3) +and DBM_LIST (db and/or gdbm). DBD odbc and DBM sdbm are unconditionally +compiled and installed, do not include these in the list. + +Whenever distributing apr-util in combination with database client +drivers, always review the license requirements of all components. + + +Cryptographic Software Notice +----------------------------- +This distribution includes cryptographic software. The country in +which you currently reside may have restrictions on the import, +possession, use, and/or re-export to another country, of +encryption software. BEFORE using any encryption software, please +check your country's laws, regulations and policies concerning the +import, possession, or use, and re-export of encryption software, to +see if this is permitted. See http://www.wassenaar.org/ for more +information. + +The U.S. Government Department of Commerce, Bureau of Industry and +Security (BIS), has classified this software as Export Commodity +Control Number (ECCN) 5D002.C.1, which includes information security +software using or performing cryptographic functions with asymmetric +algorithms. The form and manner of this Apache Software Foundation +distribution makes it eligible for export under the License Exception +ENC Technology Software Unrestricted (TSU) exception (see the BIS +Export Administration Regulations, Section 740.13) for both object +code and source code. + +The following provides more details on the included cryptographic +software: + + APR-Util provides an abstract interface for symmetrical cryptographic + functions that make use of a general-purpose encryption library, + such as OpenSSL, NSS, or the operating system's platform-specific + facilities. This interface is known as the apr_crypto interface, + with implementation beneath the /crypto directory. + + APR-Util provides an abstract interface for SSL encrypted LDAP (ldaps + and STARTTLS style) connections, which can be powered by OpenLDAP, + Netscape LDAP SDK, Mozilla LDAP SDK, or other platform specific ldap + interfaces. + |
