3 # This script constructs the "sqlite3.h" header file from the following
6 # 1) The src/sqlite.h.in source file. This is the template for sqlite3.h.
7 # 2) The VERSION file containing the current SQLite version number.
8 # 3) The manifest file from the fossil SCM. This gives use the date.
9 # 4) The manifest.uuid file from the fossil SCM. This gives the SHA1 hash.
11 # Run this script by specifying the root directory of the source tree
12 # on the command-line.
14 # This script performs processing on src/sqlite.h.in. It:
16 # 1) Adds SQLITE_EXTERN in front of the declaration of global variables,
17 # 2) Adds SQLITE_API in front of the declaration of API functions,
18 # 3) Replaces the string --VERS-- with the current library version,
19 # formatted as a string (e.g. "3.6.17"), and
20 # 4) Replaces the string --VERSION-NUMBER-- with current library version,
21 # formatted as an integer (e.g. "3006017").
22 # 5) Replaces the string --SOURCE-ID-- with the date and time and sha1
23 # hash of the fossil-scm manifest for the source tree.
25 # This script outputs to stdout.
