Log Message:
-----------
- added script to measure start-up time of LanguageTool
in all languages on a given input sentence (empty sentence
by default). It can be useful to check for regression in
speed and to compare speed of LanguageTool in different
languages. See comments in script for a description
of how to run it. It has already proven to be useful
in 2 occasions:
* it helped to identify that SRX was slow (improved
later in r6741 thanks to Jarek Lipski).
* it identified that Hunspell initialization was
slow even when turning off Hunspell rule with
-d HUNSPELL_RULE (fixed in svn r7247 by Daniel Naber
with lazy intialization).

+# This script measures how long it takes to start up
+# LanguageTool with an empty input for each language.
+# 3 samples are measured to avoid outliers.
+# It also prints the number of XML rules for each language.
+#
+# Example:
+#
+# $ cd languagetool/src/scripts
+# $ ./startup-time-lt.sh
+#
+# or to measure timing with a sentence "foo bar":
+#
+# $ ./startup-time-lt.sh "foo bar"
