+usage: $name [options]
+
+  Manage compilation of SA-Hiero files and creation of ini files.
+  In the default usage, the command deploys a set of files needed
+  to create a system, and writes an ini for the system on stdout.
+
+options:
+
+  -a, --alignment <name>[=<filename>]
+    Name of an alignment of a bitext (which must be specified 
+    with -b unless using the -c flag).  If used with -r, the 
+    alignment is removed from the deployment.  If used with -c, 
+    only alignments with this name are listed.  If a filename is 
+    given, then the file will be deployed using the name.
+
+  -b, --bitext <name>[=<f file>,<e file>]
+    Name of a bitext for a particular system type (which must be
+    specified with -t unless using the -c flag).  If used with -r,
+    the bitext is removed from the deployment.  If used with -c,
+    only bitexts with the name are listed.  If a filename is given,
+    then the file will be deployed using the name.
+
+  -h, --help
+    Prints this message.
+
+  -i, --ini <filename>
+    Use a specific ini file as the template for a system, rather than
+    the default ini file.
+
+  -p, --precomp-options <key1>=<value1>[,<key2>=<value2>,...,<keyN>=<valueN>]
+    Set parameters of the grammar.  This must be set by $name because
+    many parameters involve precomputation.  There are six keys that can
+    be set: 
+      max-len: maximum number of symbols (T and NT) in a grammar rule
+      max-nt: maximum number of nonterminals in a grammar rule
+      max-size: maximum span of a grammar rule extracted from training
+      min-gap: minimum gap spanned by a nonterminal in training
+      rank1: number of frequent words to precompute collocations for.
+      rank2: number of super-frequent words to precompute triple 
+        collocations for.
+    All values must be positive integers.  If not specified, defaults are:
+      max-len = 5
+      max-nt = 2  (>2 not supported)
+      max-size = 10
+      min-gap = 2
+      rank1 = 100 (>300 not recommended)
+      rank2 = 10  (>10 not recommended)
+
+  -n, --no-ini
+    Do not generate an ini file on stdout.  If this option is used, then
+    the requirement to specify a full system is relaxed.  Therefore, this
+    option can be used when the sole objective is deployment of files.
+
+  -o, --output-dir
+    Write the compiled model to this directory.
