+# IBM Tivoli Storage Manager Client uses a system-wide
+# client system-options file `dsm.sys` and expects it
+# to be located in a directory within the package.
+# Note that the command line client and the API use
+# different "dms.sys" files (located in different directories).
+# Since these files contain settings to be altered by the
+# admin user (e.g. TSM server name), we create symlinks
+# in place of the files that the client attempts to open.
+# Use the arguments `dsmSysCli` and `dsmSysApi` to
+# provide the location of the configuration files for
+# the command-line interface and the API, respectively.
+#
+# While the command-line interface contains wrappers
+# that help the executables find the configuration file,
+# packages that link against the API have to
+# set the environment variable `DSMI_DIR` to
+# point to this derivations `/dsmi_dir` directory symlink.
+# Other environment variables might be necessary,
+# depending on local configuration or usage; see:
+# https://www.ibm.com/support/knowledgecenter/en/SSEQVQ_8.1.8/client/c_cfg_sapiunix.html
+
+
+# The newest version of TSM client should be discoverable

+      IBM Spectrum Protect (Tivoli Storage Manager) provides
+      a single point of control for backup and recovery.
+      This package contains the client software, that is,
+      a command line client and linkable libraries.
+
+      Note that the software requires a system-wide
+      client system-options file (commonly named "dsm.sys").
+      This package allows to use separate files for
+      the command-line interface and for the linkable API.
+      The location of those files can
+      be provided as build parameters.
